I can work around the issue by zooming out a bit in the Firefox window, perhaps there is a clue there. I find this necessary for configuring scheduled reports.

Also, I will get the same problem with popup controls with certain Application Themes applied.

System: Fedora 33, KDE Plasma desktop. Firefox 85.

I have the same problem with JSR7.8.0 and Firefox 86.
DropdownList is closing immediately when trying to select an item .
I've no workaround, neither the mentioned css or popupselect or zooming out.

pls help.


I have the same problem with firefox 85.0.2.
The workaround of setting control display mode to pop-up and zooming out works for me, but I'm looking for better solution.
