Bug ID: 54089
           Summary: user32:input - test_SendInput() sometimes gets an
                    unexpected 0x738 message on w1064v1709
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: user32
          Assignee: [e-mail]
          Reporter: [e-mail]

test_SendInput() sometimes gets an unexpected 0x738 message on w1064v1709:

* 2022-060-14
  input.c:4439: Test failed: SendInput triggered unexpected message 0x60
  input.c:4457: Test failed: SendInput triggered unexpected message 0x738

* 2022-12-05
  input.c:4560: Test failed: SendInput triggered unexpected message 0x60
  input.c:4578: Test failed: SendInput triggered unexpected message 0x738

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

It's not clear why this only happens on w1064v1709.

I suspect this is a repeat of bug 48815 where this 0x738 message was being sent
to a message-only UserAdapterWindowClass window (but apparently that impacted
all Windows 10 >= 1709). If so maybe user32:input should selectively ignore
some messages like user32:win now does:

user32/tests: Ignore messages for UserAdapterWindowClass windows.
