KDE 5.27 after tiling

SUMMARY
In KDE 5.27, quick tiling a window would make the window decorate itself as if it was maximized. This is most noticeable in Firefox, where the empty "grabber" section in the upper left of the title bar goes away when maximized. It is also noticeable in that window corners appear curved normally, but rectangular when maximized.

In KDE 6.0.4, quick tiled windows still have curved corners, and Firefox still shows that large empty "grabber" section.

STEPS TO REPRODUCE
1. Launch Firefox
2. Windows + Left (or drag to left edge of screen to trigger Quick Tile)
3. Note upper left of Firefox titlebar

OBSERVED RESULT
Still has large empty "grabber" area, still has rounded corner showing desktop below.

EXPECTED RESULT
Grabber area should be gone, corners of window should be rectangular.

This is because we're working around a GTK bug in 6.0, which made it impossible to resize tiled GTK windows. It should work as expected again in 6.1
