At least on X11, no SDL_WINDOWEVENT_RESTORED event is emitted after the window was unminimized.

This was caused by this commit:
SDL-mirror/SDL@abcfcda

Reason:
In X11_DispathEvent on PropertyNotify on _NET_WM_STATE property change, if unminimized is happens, X11_DispatchMapNotify is called:
https://github.com/SDL-mirror/SDL/blob/master/src/video/x11/SDL_x11events.c#L1295

X11_DispatchMapNotify tries to emit two events:

• first SDL_SendWindowEvent(SDL_WINDOWEVENT_SHOWN) which resets the minimized flag (see commit),
• then SDL_SendWindowEvent(SDL_WINDOWEVENT_RESTORED) which expects minimized flag set, but it was reset by previous SHOWN event and hence it bails out not emitting RESTORED event:
  https://github.com/SDL-mirror/SDL/blob/master/src/events/SDL_windowevents.c#L142
