Summary

• A context-menu row whose toggle_layer_render target is a layer never showed a check mark, even while that layer was drawing. context_menu_action_flags resolved the target against theme.surfaces only, so checked stayed false for every layer target.
• The action itself resolves the target differently: execute_context_menu_action runs toggle("<target>", render) through execute_mouse_action_source in the surface the menu was opened from, where layers do resolve. So the row toggled the layer correctly but reported no state back.
• Resolve the flag the same way the action does: a surface id first, keeping the existing behaviour, otherwise a layer in the origin surface, reporting its live render state. An id that matches neither reports no state and stays unchecked instead of guessing.
• The lookup moved into toggle_layer_render_state so it can be covered without window state. No behaviour change for toggle_provider, toggle_widget, or surface targets.

To reproduce before the fix: give a theme a menu row with {"type": "toggle_layer_render", "target": "<layer id>"}. Clicking it shows and hides the layer, but the row is never checked, unlike a toggle_provider row.

Testing

Windows 11, Rust 1.95.0 (MSVC), release profile:

• cargo fmt --all -- --check — clean.
• cargo build --locked --release — success.
• cargo test --locked --release — 619 passed, 0 failed, 6 ignored.
• New regression test window::window_context_menu::tests::a_layer_toggle_row_reports_the_layer_state_a_surface_row_already_reported: a surface id still reports the surface, a visible layer id now reports Some(true), the same layer with render = 0 reports Some(false), and an unknown id reports None. It uses ThemeDocument::starter() and no credentials or live provider requests.
• Manual check in the taskbar widget on Windows 11, with a theme whose menu rows target the two layers of a split Claude block: both rows now show a check mark while their layer draws, hiding a layer clears its check mark, and the toggle_provider row next to them is unaffected.
