d3d9:device - test_reset_fullscreen() gets an unexpected WM_SIZE message with
fvwm:

device.c:4822: Test failed: Received unexpected WM_SIZE message.

https://test.winehq.org/data/patterns.html#d3d9:device

This failure happens on cw-gtx560, cw-rx460 and debian11 VM which all run
Debian 11 with fvwm, and on debiant VM which runs Debian Testing with fvwm.

But it does not happen on fg-deb64 which runs Debian 11 too, but with KDE's
window manager.

So it is pretty likely that this failure only happens when running fvwm.
