This seems to be regression since commit: https://git.libreoffice.org/core/commit/06fb3e7b7f1079c276ad2f048cd94299b4bd7006 It is observed in openSUSE integration for KDE interface: https://openqa.opensuse.org/tests/1338437#step/ooffice/6 Problem is not present on Gnome build.
Hmm - so I tested a lot of stuff, but missed the missing (keyboard) focus for new dialog windows :-( This is IMHO a far worse problem, then the popup. Guess I will just revert it, since I currently don't have time to look further into it and 6.4.6 is already in RC phase.
