Do you know why this becomes empty? AFAIK, the minimized window is simply hidden
and doesn't change the bounds or transform.

A transform is applied on he window on minimize, with scale = 0! That causes the
window bounds to be empty (I was pretty surprised when I noticed this).

Ah, I think it's coming from minimize animation. Let me double check if we're
keeping that by design or something else.
