Screen recording of the bug

SUMMARY
Opening properties of a file / folder for the first time in dolphin under X11
messes up window management badly.
The dolphin window is hidden for a short time, then re-appears at a different
position, along with the properties dialogue.

STEPS TO REPRODUCE
1. Open a fresh instance of dolphin in X11 (maybe also Wayland, untested)
2. Right click a folder or file
3. Click on properties

OBSERVED RESULT
Dolphin window unaffected, dialogue window opens

EXPECTED RESULT
A whole lot of mess (see attached video)

ADDITIONAL INFORMATION
Unfortunately the whole thing happens way too fast so I couldn't get any decent
x properties info or the likes.
Neither kwin nor dolphin give any helpful output on stdout or stderr  (except
some potentially unrelated qml warnings).
Window manager is kwin, mostly default settings, no window rules for dolphin as
far as I can spot. 
Reproducible on my laptop (same software versions) with an Intel GPU, thus
unrelated to graphics stack or drivers.
