* Fix headless cleanup race: dispose before signalling TCS (#20664)
Restructure DispatchCore<TResult> so application.Dispose() runs in a
finally block before tcs.TrySet* is called. Previously, the using-var
scope closed after TrySetResult, leaving s_uiThread set when the next
non-headless test started.
Adds a regression test in IsolationTests that verifies Dispatcher.UIThread
is accessible from the calling thread immediately after a headless dispatch
completes (PerTest isolation only).
* Use Assert.SkipWhen in Dispatch_Cleanup_Should_Complete_Before_Task_Returns
* Restrict Dispatch_Cleanup_Should_Complete_Before_Task_Returns to NUnit
xUnit's AvaloniaFactDiscoverer wraps every [Fact] in session.Dispatch,
so awaiting another session.Dispatch inside the test body deadlocks on
the session's single background thread.
* Remove new test
It isn't reliable enough during CI.

* Fix#20816: OneWay binding fails to update target after local change
When a OneWay binding target is modified locally (e.g., via user
interaction on a ToggleButton), subsequent PropertyChanged events from
the source were being ignored. This occurred because the binding
expression incorrectly suppressed the update.
This patch modifies UntypedBindingExpressionBase to ensure that OneWay
bindings always propagate changes from the source to the target,
overriding any previous local changes. Unit tests were also added to
prevent future regressions on this behavior.

* fix: focus correct date selector for day-first locales in DatePickerPresenter
SetInitialFocus had a copy-paste bug where the day-first branch
focused _monthSelector instead of _daySelector. This caused every
locale that puts day first (UK, Europe, Australia, India — dd/MM/yyyy)
to focus the wrong selector when the picker opened.
Refactored the three near-identical if/else branches into a
data-driven loop that pairs each host panel with its selector,
making this class of copy-paste bug structurally impossible.

* fix: check format key in DataTransferItem.FindAccessor single-item path
The single-item fast path in FindAccessor returned the stored value for
any format query without checking if the requested format matched.
This caused TryGetRaw to return wrong data when queried with a format
different from the one stored (e.g., querying Bitmap on a text-only item
returned the text value instead of null).
Add the missing singleItem.Key.Equals(format) check, consistent with
the dictionary path (TryGetValue) and RemoveCore.

* test: add DataFormat.CreateInProcessFormat tests
Cover the new InProcess format API: kind, identifier, null/empty
validation, non-ASCII identifiers, HasSystemName for all four kinds,
ToSystemName throwing, equality/inequality, DataTransferItem
integration, and coexistence with other formats in DataTransfer.
* feat: implement DataFormat.CreateInProcessFormat<T> for in-process drag/drop
Add DataFormatKind.InProcess and DataFormat.CreateInProcessFormat<T>()
so users can pass arbitrary object references during in-process
drag-and-drop without crossing serialization boundaries.
- Add HasSystemName property to indicate whether ToSystemName() is valid
- Update ToSystemName to throw for InProcess (same as Universal)
- Guard all 7 platform backends (Win32, macOS, X11, Android, Browser,
iOS) to skip InProcess formats during clipboard/drag-drop enumeration
Closes#20097
* fix: remove HasSystemName API per review feedback
* test: add regression test for access key with system key events
Regression test for #20961: verifies that access keys fire correctly
when triggered via Alt+key (system key events).
* fix: provide KeySymbol for system key events via MapVirtualKey
On Windows, WM_SYSKEYDOWN (Alt+key) intentionally skips ToUnicodeEx
to avoid corrupting keyboard state. This left KeySymbol null, which
broke access keys after #20662 switched from Key to KeySymbol.
Use MapVirtualKey(VK, MAPVK_VK_TO_CHAR) as a layout-aware fallback
for system key events — it resolves the character without touching
keyboard state.
Fixes#20961
