[PATCH 0/1] MR667: win32u: Ignore SetWindowPos() if it is trying to change topmost state for child window.

[Paul Gofman (＠gofman)]

I think the behaviour of SetWindowPos() in this case is partially explained by the fact that topmost state is not strictly applicable to child windows and so Windows denies such requests. Child window can still end up with WS_EX_TOPMOST style if it was set at window creation (doesn't work this way in Wine now) or, e. g., like in the test added in the patch.
