[PATCH v6 0/2] MR419: win32u/window: Ignore changing WS_EX_TOPMOST for message-only windows.
-- v6: win32u/window: Ignore changing WS_EX_TOPMOST for message-only windows. user32/tests: Check that message-only windows ignore WS_EX_TOPMOST. https://gitlab.winehq.org/wine/wine/-/merge_requests/419
From: Giovanni Mascellani <gmascellani(a)codeweavers.com> libOVR brings a message window topmost claiming that this way it receives WM_DEVICECHANGE faster. Currently, in Wine, this causes a WM_KILLFOCUS to be sent to the actual topmost window, which in turn causes "Shantae: Risky's Revenge" to minimize. The effect is that the game automatically minimizes as soon as it is launched, which is incorrect.

It seems that (at last!) all the outstanding testbot errors are unrelated to this patch. In the last version I had to compromise a little bit to avoid making the test too brittle, but it should still test for the behaviour required by the game and at the same justify the change. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/419#note_4579
