[PATCH 0/1] MR9498: win32u: Use 0x20 for iconic WM_ACTIVATE message wparam.

[Rémi Bernon (＠rbernon)]

Found while doing tests for https://gitlab.winehq.org/wine/wine/-/merge_requests/9398, although it seems that we wont be able to write proper tests because of fvwm limitations with minimized windows.

[PATCH 1/1] win32u: Use 0x20 for iconic WM_ACTIVATE message wparam.
