- Added `IInputRoot Root` property to `RawInputEventArgs`
- Removed `InputRoot` and `Root` properties from `RawDragEvent` and `RawPointerEvent` as its now in the base class
- `InputRoot` in `RawDragEvent` was incorrectly using the type `IInputElement` instead of `IInputRoot`, fix callers that were using the wrong type
- Pass the input root to all raw input event constructors
- If no control is focused in `KeyboardDevice.ProcessRawEvent` then raise the event on the root
And implement the functionality in the content controls themselves. `ContentControlMixin` was too complex and even with its complexity had bugs (such as in #2821). By moving the functionality to the content controls there is some repeated code but it's much more straightforward.
After the selected item is removed from a `ListBox` with `AlwaysSelected == true`, the container for the newly selected item does not get `:selected` applied.
#2431 erroneously removed the `.Constrain(availableSize)` call in `Layoutable.Measure`. Now that the WPF source is available, I can see i that WPF does in fact constrain measure to availableSize and Grid relies on this.
Put constraint back in, undo the changes to the controls changed in #2431 (`StackPanel`, `Image`) and update the expected test results based on cross-checks with WPF in https://github.com/wieslawsoltes/WpfUnitTests/pull/1.
Previously a dangling reference to `ContentPresenter` was left in place in the ex-child control's `InheritanceParent`. When the child is removed from the `ContentPresenter`, reset the value to the control's logical parent.
