Last closed window still sends events after being dropped

[skyrina]

Description

I have a program that manages windows using a HashMap<WindowId, Window>. After removing a window from the hashmap, and even manually calling drop() on it, it still continues to receive events (although the "destroyed" event is expected).

In the log below, I created two windows, closed one, clicked on my desktop, then closed the second window and clicked again. Each click resulted in two ModifiersChanged events for the last closed window, one for holding the click down and another for releasing it, despite the window being dropped:

received event RedrawRequested from nonexistent window WindowId(67108874)
received event Destroyed from inexistent window WindowId(67108874)
received event ModifiersChanged(Modifiers { state: ModifiersState(0x0), pressed_mods: ModifiersKeys(0x0) }) from inexistent window WindowId(67108874)
received event ModifiersChanged(Modifiers { state: ModifiersState(0x0), pressed_mods: ModifiersKeys(0x0) }) from inexistent window WindowId(67108874)
received event RedrawRequested from nonexistent window WindowId(67108867)
received event Destroyed from inexistent window WindowId(67108867)
received event ModifiersChanged(Modifiers { state: ModifiersState(0x0), pressed_mods: ModifiersKeys(0x0) }) from inexistent window WindowId(67108867)
received event ModifiersChanged(Modifiers { state: ModifiersState(0x0), pressed_mods: ModifiersKeys(0x0) }) from inexistent window WindowId(67108867)
