Hi folks, I don't know is it make sense for investigation, but for my curiosity
I was tried to research it myself.
I've using desktop Intel UHD630 with two monitors, primary on DP and secondary
on HDMI. 
And on my setup I need often to effectively unplug-plug DP monitor via KVM
switch, while HDMI connected permanently, so I experiencing this kind of bugs a
lot during work.
Maybe this bug related to "Primary Monitor" feature? If I remove Q_EMIT
primaryOutputChanged(primary); in Platform::setPrimaryOutput I can switch
monitor back and forth and plasmashell doesn't loose containment on secondary
monitor.

I've spot another strange behavior with Primary Monitor feature and commented
this
https://invent.kde.org/plasma/kwin/-/commit/f91ae3e97584767d273479c4013a43e279d77f40#note_383499
but not really sure is it related or not.

PS: A bit off-topic, but can we introduce settings for ignoring hot-plug events
from monitors? I actually can use wayland only after removing updateOutputs
from DrmBackend::handleUdevEvent, otherwise after switching KVM back and forth
some windows on desktop changes their positions, a bit annoying.
