Bug ID: 53435
           Summary: user32:msg - test_SendMessage_other_thread() sometimes
                    fails on Windows 7
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: user32

user32:msg - test_SendMessage_other_thread() sometimes fails on Windows 7:

msg.c:18505: Test failed: wrong status 00400040

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

Where 0x00400040 that there are still QS_SENDMESSAGE messages in the queue and
that one was added since the last call.

This is similar to the Windows 10-only bug 53434 but the status is different
and this failure only happens on Windows 7.
