Mnemonics for menu containing numeric text not working

ADDITIONAL SYSTEM INFORMATION :
Win 10, OpenJDK 17, OpenJFX 17.0.0.1

A DESCRIPTION OF THE PROBLEM :
I've had mnemonics for several releases with no issues. I just updated to JavaFX 17.0.0.1 and mnemonic parsing for a menu which contains only numbers doesn't work as expected. When the app is run the menu text begins with the '_' and mnemonic doesn't work.

All other mnemonics work as in previous versions.

I tested this with OpenJDK16 and OpenJFX 17 and observed the same behavior so I'm assuming the change occurred due to OpenJFX 17.

A few other tests showed that a numeric mnemonic doesn't work regardless of where in the menu text it present.



FREQUENCY : always
