When transitioning a window from IconicState to NormalState and the window is managed, go through WithdrawnState. This is needed because Mutter doesn't unmap windows when making windows iconic/minimized as Mutter needs to support live preview for minimized windows. So on Mutter, a window can be both iconic and mapped. If the window is mapped, then XMapWindow() will have no effect according to the XMapWindow() documentation. Thus we have to transition to WithdrawnState first, then to NormalState.
