Bug 509270

SUMMARY
Some custom tiled windows are incorrectly re-tiled when switching virtual desktops, or when other windows are minimized

Setup
Have at least two virtual desktops

STEPS TO REPRODUCE
This can be reproduced with a single display
1. Open Kate and KWrite
2. Tile Kate to the left third with a shortcut (custom tiling via the Mudeer plugin)
3. Tile KWrite to middle third with a shortcut
4. Switch to another virtual desktop, and then back

OBSERVED RESULT
Kate retains its tiling
KWrite is tiled on the right half, rather than how it had been sized / tiled

EXPECTED RESULT
Window size and tiling is unchanged

Another way to reproduce:
This I cannot trigger on a single display, only when I have my laptop docked and connected to an external monitor
1. Open two Firefox windows
2. Custom tile one to the left third
3. Custom tile the other to the middle third
4. Minimize one of the two windows

OBSERVED RESULT
The non-minimized window tiles to take up half the screen
