[Bug 54594] dinput:device8 - test_dik_codes() sometimes gets timeouts on the GitLab CI

--- Comment #2 from Rémi Bernon  ---
I can finally reproduce it locally, and I believe that it is a race condition
in fvwm. The WM sends WM_TAKE_FOCUS messages to us, with some timestamp to use
for the reply, but quickly after calls XSetInputFocus on its own desktop window
with CurrentTime.

Depending on how quickly we reply to the WM_TAKE_FOCUS message, this ends up
with fvwm stealing our focus and we get a FocusOut even right after the FocusIn
event. We then set focus to desktop, as we should, and wineserver stops sending
input to the dinput messages window.
