Bug ID: 58692
           Summary: Incorrect owner-owned windows z-order support
           Product: Wine
           Version: 10.0
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: user32

I create two WS_OVERLAPPED or WS_PPUP (not having WS_CHILD!) windows, one is
owned by another:

hwnd1 = CreateWindow(....., 0,  .....);
hwnd2 = CreateWindow(....., hwnd1, .....);

In Windows hwnd2 is allways placed over hwnd1 and hides when hwnd1 is
minimized. In Wine itself (when graphics options do not allow Window Manager to
arrange and decorate Wine windows) hwnd1 and hwnd2 act as windows of the same
level: when hwnd1 is activated it is displayed over hmnd2 and vise versa -
WHY?! This is the basic windows behaviour, why it is incorrect?

If Window Manager is allowed to manage&decorate Wine windows, the behaviour is
more similiar to one under native Windows, but with another problems:

- "minimize" buttons of all windows are hidden for some unknown reason...

- if we have hwnd2 and hwnd3 as owned windows of hwnd1, and hwnd1, then hwnd2,
then hwnd3 are activated - and hwnd3 is closed - hwnd1 is activated instead of
previously active hwnd2 - differs from native Windows behaviour.
