Bug ID: 54357
           Summary: Spurious fixme message when calling ScrollWindow()
           Product: Wine
           Version: 8.0-rc3
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P2
         Component: user32
          Assignee: [e-mail]

`ScrollWindow()` calls `NtUserScrollWindowEx()` with `SW_NODCCACHE` in the
flags, but this function complains if it's passed anything other than
`SW_SCROLLCHILDREN | SW_INVALIDATE | SW_ERASE`.

This seems to be due to a relatively recent b2db69efcf4 (win32u: Move
NtUserScrollWindowEx implementation from user32., 2022-06-08) as it replaced
the call to the internal `scroll_window()` with a call to
`NtUserScrollWindowEx()` with this unrecognized flag.
