BitPhoneInput gains formatted and normalized phone values, country-priority resolution, masking, strict input, search, keyboard navigation, responsive rendering, accessibility attributes, templates, public control methods, expanded demos, and comprehensive tests.

Changes

PhoneInput improvements

Layer / File(s) Summary
Country priority and dialing-code contract
src/BlazorUI/Bit.BlazorUI.Extras/Components/Flag/BitCountry.cs, src/BlazorUI/Bit.BlazorUI.Extras/Components/Flag/BitCountries.cs
Adds Priority and cached DigitsCode. Shared dialing-code countries receive region priorities.
PhoneInput rendering and behavior
src/BlazorUI/Bit.BlazorUI.Extras/Components/PhoneInput/*
Adds masking, strict input, ranked search, keyboard navigation, responsive callouts, templates, clear actions, E.164 normalization, two-way IsOpen, and accessibility attributes.
PhoneInput styling and support
src/BlazorUI/Bit.BlazorUI.Extras/Components/PhoneInput/BitPhoneInput.scss, src/BlazorUI/Bit.BlazorUI.Extras/Components/PhoneInput/BitPhoneInputClassStyles.cs, src/BlazorUI/Bit.BlazorUI.Extras/Scripts/Extras.ts
Adds size, disabled, clear-button, border, underline, required, and responsive styles. Modifier-key combinations are excluded from key suppression.
Demo and validation coverage
src/BlazorUI/Demo/Client/Bit.BlazorUI.Demo.Client.Core/Pages/Components/Extras/PhoneInput/*, src/BlazorUI/Tests/Bit.BlazorUI.Tests/Components/Extras/PhoneInput/BitPhoneInputTests.cs
Expands the demo to 25 examples and adds coverage for component rendering, values, interaction, accessibility, templates, binding, and public methods.

Merge Risk: 🟡 Moderate · up to 37e14

Programmatic dropdown control can fail to update the UI, while search or parsing can throw under supported mutation or concurrent access. Focus styling is also lost for several variants, so these issues should be fixed before merge.

Inline comments:
In `@src/BlazorUI/Bit.BlazorUI.Extras/Components/Flag/BitCountry.cs`:
- Around line 56-62: Update the DigitsCode cache in the BitCountry getter to
capture the settable Code value once, compute _digitsCode from that snapshot,
and publish the associated key only after the value is fully initialized using
acquire/release synchronization. Ensure readers cannot observe a matching
_digitsCodeOf while _digitsCode is null, preserving correct behavior for shared
BitCountry instances.

In
`@src/BlazorUI/Bit.BlazorUI.Extras/Components/PhoneInput/BitPhoneInput.razor.cs`:
- Around line 434-441: Update OpenAsync and CloseAsync in BitPhoneInput so each
successful callout operation invokes StateHasChanged after OpenCallout or
CloseCallout completes, while retaining Task.CompletedTask for operations that
are not applicable or already in the requested state.
- Around line 733-735: Update BuildItems to return a copy of Countries when
PreferredCountries is empty, rather than the original list instance. Preserve
the existing preferred-country ordering behavior while ensuring _allItems
changes when the source collection is mutated, so OnParametersSet rebuilds
_foldedNames and _foldedWords consistently.

In `@src/BlazorUI/Bit.BlazorUI.Extras/Components/PhoneInput/BitPhoneInput.scss`:
- Line 542: Restore the parent selector in the four focus-rule sites in
BitPhoneInput.scss: at lines 542, 416-418, and 451-454 use the variant’s parent
selector with .bit-phi-fcs, and at line 508 apply the error focus ring to both
.bit-phi-err.bit-phi-fcs and .bit-inv.bit-phi-fcs. This must produce
same-element variant/focus selectors and restore all affected focus rings.
- Around line 525-540: Preserve the nested .bit-phi.bit-dis override within the
phi-color styles, including the disabled border color assignment in
.bit-phi-drp. Ensure disabled BitPhoneInput elements retain $clr-brd-dis even
when Color is BitColor.Error and later error styles apply.

In
`@src/BlazorUI/Demo/Client/Bit.BlazorUI.Demo.Client.Core/Pages/Components/Extras/PhoneInput/BitPhoneInputValidationModel.cs`:
- Line 8: Update the RegularExpression attribute in BitPhoneInputValidationModel
to replace \d with [0-9], while preserving the existing international
phone-number format, length limits, anchoring, and error message.

In
`@src/BlazorUI/Tests/Bit.BlazorUI.Tests/Components/Extras/PhoneInput/BitPhoneInputTests.cs`:
- Around line 924-927: Update the affected public-API tests around OpenAsync and
CloseAsync to return async Task, await every component.InvokeAsync call, and
include the call near line 943 so component operations and callback failures
complete before assertions run.
