[Bug 60404] New: EndDeferWindowPos succeeds with HWNDs that don't share the same parent

            Bug ID: 60404
           Summary: EndDeferWindowPos succeeds with HWNDs that don't share
                    the same parent
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P2
         Component: user32
          Assignee: [e-mail]
          Reporter: [e-mail]
  Target Milestone: ---
      Distribution: ---

MSDN mentions that any HWND provided to DeferWindowPos should share the same
parent. Tests show Windows doesn't report any failure on DeferWinodwPos when
you're calling it with a window that has a different parent and
EndDeferWindowPos returns TRUE too, but even though it returns TRUE it doesn't
move any window and GetLastError() returns ERROR_HWNDS_HAVE_DIFF_PARENT. WINE's
behavior is inconsistent with Windows, and while it should fail it doesn't.

Is there an app that depends on this?

I don't know about apps being dependent on this behavior, but I discovered this
while I was working on a Win32 app. I was using WINE to debug it, and then when
I was wondering why the project doesn't work on Windows while it works fine on
WINE, I discovered this inconsistency.

OK, thanks. In general we don't try to replicate that kind of behavior, because
if it fails on Windows, presumably no app is going to do that.

I understand, that's why I would call it a "trivial" bug.
