[Bug] Window stays fullscreen and untilable after being fullscreened while floating

[Piotrekol]

Describe the bug

Workaround exists, but wasn't obvious at first: window can be manually re-tiled via toggle-tiling (alt+t).

Reproduction

1. Focus floating window
2. Fullscreen it using toggle-fullscreen
3. Un-fullscreen it again using toggle-fullscreen
4. Attempt to re-tile using toggle-floating - window is not tiled, and visually is still fullscreen
