ADDITIONAL SYSTEM INFORMATION :
Windows 10

A DESCRIPTION OF THE PROBLEM :
Pressing ALT does activate Mnemonic keys, so pressing the corresponding key for a button will press the button. This works fine.


But in Windows, pressing Alt + Tab will switch to a different application. Pressing again Alt-Tab will switch back to the JavaFx application - this works fine. Switching back will find the button in the Mnemonic active state, so pressing a letter will trigger the button.

The fix for this would be to clean mnemonic activation each time an application goes in background.

REGRESSION : Last worked in version 13.0.2
