SUMMARY
When resizing a window with 2 monitors (one higher res than the other), it is possible to move it outside of the smaller monitors range

STEPS TO REPRODUCE
1. Have 2 monitors
2. move the window to the smaller monitor
3. grab the window at the bottom of the title bar, and move it up quickly

OBSERVED RESULT
Its possible to get the title bar outside of a clickable range, making it impossible to move back/size inbounds

EXPECTED RESULT
It prevents you from doing that

I can reproduce this on git-master using the steps to reproduce. On step 3 I had to move the window to the left, rather than up.
I tested with Dolphin.

To get the window to be fully on the display again I had to use
Right click on tray icon -> More -> Move
