SUMMARY
Plasma hard and complete freeze/lock up while dragging a window along the top edge of the desktop on Wayland. This has happened on both 6.3.0 and now 6.3.1. It seems to be the maximize detection code (even if disabled) that is triggering this. With it enabled I can visually see the maximize feedback trigger when it locks, while with it disabled the mouse and window stutter and slow way down until you pull the window back down. After 3-6 maximize attempts (because dragging horizontally across the top edge is difficult without accidentally pulling the window off the top of the screen) is when it locks.

STEPS TO REPRODUCE
1. With or without "Windows dragged to top edge" set, have a window snapped (non-tiling) to top of screen.
2. Drag the window left and right not leaving the snapped top but occasionally your mouse may try to pull the window slightly above the top of the window (as if triggering a top edge maximize even if that is disabled).
3. After 3-5 seconds of back and forth movement (like you are trying to position it precisely where you want it and triggering the maximize detection code several times), the screen freezes.

OBSERVED RESULT
The screen completely locks up. Mouse and keyboard unresponsive so unable to get any logs or restart kwin. Have to hard power off/on.

EXPECTED RESULT
Not lock up but continue to allow moving the window.
