jsdom is feeling the AGI!

This release is dedicated to @​scttcper, who unleashed @​codex upon jsdom and found tons of performance improvements. Along the way, he found and fixed many correctness issues as well.

We really appreciate his thoughtful PRs, which did a great job following the project's contribution guidelines, and were clearly human-curated, with their PR descriptions edited to be brief and respectful of the maintainers' time.

Thanks to @​scttcper, as well as all the other contributors of this release (most of whom were AI-assisted).

  • Added named access to elements on document, such as document.myForm for <form name="myForm">. (@​vojtisprime11)
  • Added QuotaExceededError, including its use for storage quota errors and oversized crypto.getRandomValues() requests.
  • Added support for the relaxed DOM naming rules when creating elements, attributes, and document types.
  • Improved performance of DOM construction, tree mutations, range operations, and live collection access, especially on large documents. (@​scttcper, @​erezrokah)
  • Improved performance of getComputedStyle(), style changes, and CSS serialization. (@​scttcper, @​jhult)
  • Improved performance of event dispatch, form control and label lookups, and updates to <select> elements and radio button groups. (@​scttcper)
  • Reduced memory use when creating and working with DOM nodes, attributes, event listeners, and mutation observers. (@​scttcper)
  • Changed window.close() to preserve access to the document and its DOM through retained references.
  • Fixed element.querySelectorAll() returning no matches when the first part of the selector matches the element itself, which regressed in v30.0.0. (@​asamuzaK)
  • Fixed case sensitivity in CSS attribute selectors, including selectors matching data-state="", title="", and other case-sensitive values. (@​asamuzaK)
  • Fixed document.querySelector() failing to find a matching element when an earlier element has the same ID but does not match the rest of the selector. (@​vojtisprime11)
  • Fixed :focus matching in shadow trees. (@​asamuzaK)
  • Fixed DOM insertion and replacement, including valid document.replaceChildren() calls, invalid document element and doctype placements, and mutations during element.replaceWith().
  • Fixed the ordering of script execution, custom element callbacks, iframe loading, and mutation observer notifications during DOM insertion, including in shadow trees.
  • Fixed queued events and navigation continuing after window.close() or iframe removal, and prevented new scripts, resource loads, timers, and animation frames from starting in destroyed documents. (@​scttcper)
  • Fixed parent documents waiting indefinitely for loading to finish when a child iframe removes itself during loading.
  • Fixed request cancellation across redirects, during pending requestInterceptor() callbacks, and when reusing an XMLHttpRequest after aborting it.
  • Fixed resource loading and JSDOM.fromURL() potentially hanging when response handling throws and response stream cleanup does not finish.
  • Fixed successful cached resource loads being treated as aborted.
  • Fixed getComputedStyle() and document.styleSheets using the wrong stylesheet order after inserting or updating <style> elements.
  • Fixed getComputedStyle() ignoring nested @import and @media rules in imported stylesheets, and returning stale results after imports finish loading.
  • Fixed style invalidation, stylesheet removal, and frame source updates in shadow trees.
  • Fixed repeated getComputedStyle() calls changing case-sensitive background URLs, and inconsistent resolution of border shorthands containing system colors. (@​scttcper)
  • Fixed computed border widths, including borderless elements incorrectly reporting 16px, which regressed in v30.0.0. (@​Alberto-BaseNet)
  • Fixed getComputedStyle() to resolve 'font-weight' keywords to numeric values. (@​tianrking)
  • Fixed getComputedStyle() to convert lengths to pixels inside CSS math functions containing percentages, and to resolve percentages in 'font-size' math functions. (@​soroushm)
  • Fixed serialization of min() and max() containing nested calc(), which regressed in v30.0.0. (@​asamuzaK)
  • Fixed CSS values mixing lengths or percentages with math functions, such as 'grid-template-columns' values containing both 100px and calc(). (@​rome-xi)
  • Fixed parsing of 'background' and 'border' shorthands with adjacent components, such as url(a.png)no-repeat, including a crash when parsing inline styles. Also fixed handling of invalid shorthand assignments and escaped or unusual characters in CSS declarations. (@​asamuzaK)
  • Fixed parsing of unitless zero values in 'flex' shorthands, such as 35 1 0, and rejection of negative 'flex-basis' lengths and percentages. (@​asamuzaK)
  • Fixed shorthand style assignments producing extra mutation records and custom element callbacks for intermediate values. (@​scttcper)
  • Fixed Range and Selection handling of CDATA sections, including boundary offsets and range cloning, extraction, deletion, insertion, and stringification. (@​scttcper)
  • Fixed text.normalize() incorrectly removing the text node or merging its siblings. (@​scttcper)
  • Fixed cloning and importing CDATA sections and processing instructions whose contents have been modified, and serialization of CDATA sections adopted into HTML documents.
  • Fixed stale named-property collections on window, and incorrect named access from empty or namespaced id="" and name="" values. (@​scttcper)
  • Fixed elements in documents created with DOMParser or document.implementation.createHTMLDocument() appearing as named properties on window and being retained in memory. (@​Iaotle)
  • Fixed memory leaks from mutation observers retaining observed nodes, abort signals retaining removed event listeners, and storage event tracking retaining closed windows. (@​scttcper)
  • Fixed storage events being sent to windows created after the storage change, and ensured surviving recipients still receive events when the source document is destroyed.
  • Fixed attribute lookups after namespace prefix changes, and namespaced attributes incorrectly affecting ID lookups and element behavior. (@​scttcper)
  • Fixed input.list in detached element trees. (@​scttcper)
  • Fixed attr.ownerDocument after setting an attribute node on an element in another document or adopting its element. (@​Kjubikstronk)
  • Fixed fresh element.getElementsByTagName() calls using the previous document's case-sensitivity rules after adoption between HTML and XML documents. (@​Kjubikstronk)
  • Fixed element.tagName returning stale casing after adoption between HTML and XML documents.
  • Fixed radio button grouping and checkedness updates for controls with different form owners, controls outside their form, unnamed controls, and canceled clicks.
  • Fixed <select> selection updates when moving options, and unintended selection resets when moving a whole <select> or changing unrelated descendants.
  • Fixed cloning <input> elements to preserve input.indeterminate.
  • Fixed focus state after removing a focused element or its ancestor, including inside shadow trees.
  • Fixed script execution when inserting children into a connected, empty <script>. (@​Kjubikstronk)
  • Fixed incorrect script execution after changes to src="", and handling of type="", for="", and event="".
  • Fixed document.currentScript during nested script execution and scripts in shadow trees.
  • Fixed event dispatch, window.event, and default passive listener handling for non-node event targets, and event dispatch when user code modifies window.constructor.
  • Fixed volumechange and ratechange events to fire asynchronously. (@​christianaurichzm)
  • Fixed DOM APIs accepting user-created proxies around DOM objects where genuine DOM objects are required.
  • Fixed XPath iterator invalidation after DOM mutations and errors for invalid result types.
  • Fixed NodeIterator traversal when its filter removes nodes.
  • Fixed fileReader.readAsText() to honor the blob's MIME type charset when no supported explicit encoding is supplied.
  • Fixed fractional seconds in time input parsing and serialization. (@​Jaybhade)
  • Fixed large input.valueAsNumber assignments for time and local date/time inputs.
  • Fixed hard wrapping of <textarea> values to use the numeric textarea.cols value.
  • Fixed document.readyState to be "complete" for documents created with document.implementation.createDocument() and document.implementation.createHTMLDocument().
  • Fixed element.translate for empty translate="" values and elements without a parent.
  • Fixed XML parsing of lone surrogates to replace them with the Unicode replacement character.
  • Fixed node.lookupNamespaceURI() for the xml and xmlns prefixes. (@​vojtisprime11)
  • Fixed <base> elements to ignore data: and javascript: URLs. (@​vojtisprime11)
  • Fixed svgElement.viewportElement inside <symbol> elements.
  • Fixed the default blobEvent.timecode to be NaN.
  • Fixed the object shape and property descriptors of CSS.
