Add special case when window is resized to zero

[PoignardAzur]

There have been reported crashes with Xilem when minimizing an app with Windows 11 (see also linebender/vello#371).

This fix is based on the solution proposed in:

I've tested it on Linux just enough to confirm it doesn't crash. Haven't tested in on Windows yet, so I'm not sure it actually fixes the crash on minimize.

This fixes the crash, but after restoring the window from the minimized state no events are processed any more. So clicking on buttons, including the X to close window, doesn't do anything.
