Using AccessKey to Close Window Causes Exception

[johnt-star]

Describe the bug

If a button is used to close a window, everything works as expected.

However, if an AccessKey is assigned to the button, then the AccessKey is invoked to close the window, an exception occurs.

Steps to reproduce the bug

AccessKey.zip

Project file included to demonstrate issue.

1. In main window, add a button that when tapped, launches a second window.
2. In second window, add a button that when tapped, closes the second window.
3. In second window, add an AccessKey for the button, that when invoked, also closes the second window.

Expected behavior

Using AccessKey to close window should not cause exception and should work the same way as tapping corresponding button.

After and access key is triggered, we will sometimes attempt to reset focus, but if the page is destruction, things can get confused.

The fix is in and scheduled for 1.5.
