A DESCRIPTION OF THE PROBLEM :
Pressing ALT-TAB and SHIFT-ALT triggers hotkeys in JavaFX.

When pressing the ALT key, the mnemonics are activated: the buttons get the mnemonic keys highlighted.
If one of these keys opens another dialog, the highlight mode should end in the first dialog.
Right now the new dialog is open normally, and when closing the second dialog the first is still in mnemonic highlight mode, which creates confusion.


FREQUENCY : always
