Description SoilpH96 2021-01-05 11:25:49 UTC 
SUMMARY

Quick tiled Wayland windows can't be maximized, either by the window decoration button or by a keyboard shortcut. However, XWayland windows work as expected.

STEPS TO REPRODUCE
1. Quick tile a Wayland native window.
2. Attempt to maximize it

OBSERVED RESULT

The window cannot be maximized. Attempting to do so appears to remove the window border, although it will be restored by retrying a second time. Detatching the window from the screen edge however will allow it to be maximized as normal.

EXPECTED RESULT

The window should be maximized normally, as observed when trying to reproduce the issue on an XWayland window.
