TW gtk4 - file-chooser in Firefox no longer executes when [Enter] is pressed - must mouse click??

All,

Tumbleweed VERSION="20260623"

   I thought this was just the zen browser invocation of the gtk4 file 
chooser, but it is also the Firefox package use of it as well. I doubt 
it is browser related at all and more gtk4 or that abominable 
xdg-desktop-chooser.

   What happens is when I choose to save any file in Firefox or zen, the 
gtk4 file-chooser is displayed as normal, but after I input the file 
name and press [Enter] nothing happens. Trying the [Enter] key on the 
keypad, same result. The dialog is not processing the [Enter] key to 
execute the save.

   Instead, I have to grab the mouse and click on "Save" to activate the 
dialog. That is new since this Tumbleweed update.

   Ideas? Why is the keypress event handler for the dialog not seeing 
the [Enter] keypress?
