Make LeafNode property nullable and return null when the binding expression
has no nodes (e.g., when using a constant source with a converter but no path).
This fixes an ArgumentOutOfRangeException that occurred when accessing
LeafNode or Description properties on such bindings.
Fixes#20441

* Fixed Selector.ValidateNestingSelector not calling overrides when iterating up through parent selectors
Changed ValidateNestingSelector to call recursively, walking up
the hierarchy of parent selectors. This means function overrides
are taken into account when walking up the tree. Now if a
selector has an OrSelector as its parent, it doesn't throw an
exception.
* Updated ToString methods to surround OrSelectors with parenthesis where useful

* Fix new brush test
* Switch order of brush parsing so known color optimizations are used
* Add more documentation comments to KnownColors
* Fix displayed text in BorderPage
InnerBorderEdge not InnerBorder
* update mouse test to better simulate clicks on captured controls
* add tap failing test
* use captured element if available as source for tap gestures
* fix height queries not matching when container name is set, remove unused query grammer
* add unit test for height container queries with name

* Fix SlicedStream.Seek(offset, SeekOrigin.End)
This fixes https://github.com/AvaloniaUI/Avalonia/issues/13604
The offset _from is applied in set_Position, so applying it also in Seek mispositions the stream. ZipArchive exposes the problem by seeking to the end to read the table of contents.
* Add tests for SlicedStream

* Fix InlineDictionary Behavior for Single Item Reassignment
Previous Behavior:
- When the `Set` method was called, it ignored the `overwrite` parameter if the dictionary contained only one item.
- This caused the `Set` method to behave like the `Add` method, leading to unexpected behavior in composition animations.
- Specifically, the second composition animation would not play because it could not replace the first animation. Instead, it was added after the first animation, preventing it from being executed.
Updated Behavior:
- The `InlineDictionary` now respects the `overwrite` parameter even when it contains only one item.
- This ensures that the second composition animation can overwrite the first one, allowing it to play correctly.
* Append unit test for InlineDictionary
* keep the `(TKey)_data` in a variable and reuse it below line 90 so we avoid a double cast
* Rename the test method
* Remove the unnecessary assignment code.
* removed duplicated code between Window.Show and Window.ShowDialog
* Handling different cases of window initial position and size + unit test
* positioning cursor on resize grip in WindowOrder_Modal_Dialog_Stays_InFront_Of_Parent_When_Clicking_Resize_Grip test
