Bug 482380

SUMMARY
Testing plasma 6 using arch's testing repositories.
I'm not sure if this bug belongs here or with qmmp, but I know it worked fine on plasma 5.27 on x11, but I can no longer drag this window around on plasma 6 on wayland. Qmmp is a music player and a themeable Qt6 app. I installed it from the arch repos. I forget if it is by default, but I believe it is. It uses a skinned theme where it draws its on decorations, but I can't actually move the app with this decoration. If I change the theme to the qt6 one they offer that looks all boxy like a generic qt app, then the kde decorations are shown and I can move the window. I just don't like that I can't use the theme for this app anymore that way. Using the super key plus mouse works though.

STEPS TO REPRODUCE
1. Install qmmp or maybe some other qt6 app that draws its own decorations.
2. Try to move the window via its window decoration.

OBSERVED RESULT
It doesn't move

EXPECTED RESULT
It should move
