user32:msg - test_SendMessage_other_thread() sometimes fails on Windows 1507 -
1909:

msg.c:18493: main: call PeekMessage
msg.c:18505: Test failed: wrong status 00080000
msg.c:18507: main: call PeekMessage
msg.c:18508: Test failed: PeekMessage should fail

https://test.winehq.org/data/patterns.html#user32:msg

Where 0x00080000 indicates that there are still QS_POSTMESSAGE messages in the
queue and that none were added since the last call.

This only happens on Windows 10 1507 to 1909.
