Panel rapid animation behaviour
SUMMARY
In system settings under window behaviour, in the Movement tab, we can set the
size of the snap zone for both the "screen edge snap zone" and the "window snap
zone". The panel seems to be considered both a window and a screen edge for the
purposes of this setting.
Since the floating panel can move, this can cause issues when the window snap
zone is larger than the screen edge snap zone. In particular the floating dock
goes back and forth between floating and attaching to the screen quickly.
I'm not sure if there's any reason why someone would want the window snap zone
to be larger than the screen edge snap zone, but it could happen accidentally.
For example if you increase the window snap zone while leaving the screen edge
snap zone to its default value, which is how I noticed it.
Could probably fix this by making the panel only count as only a screen edge,
not a window.
STEPS TO REPRODUCE
1. Go to System Settings > Window Behaviour > Movement
2. Set screen edge snap zone to some value smaller than the window snap zone
(say 15 px and 30 px)
3. Move a window close to the floating panel
OBSERVED RESULT
The panel attaches and floats from the edge of the screen in quick succession
EXPECTED RESULT
The panel only attaches once to the screen
