4. Switch the desktop

OBSERVED RESULT
Window loses its tiling, reset to its original size and position

EXPECTED RESULT
Window keeps its tiling

I can reproduce the issue. Not sure if this is intentional behavior or not (though if it is; I agree it feels odd). I'll let the KWin folks take it from here.
