It's common that popup2 triggered from an existing popup1, later when mouse moved to popup2, popup1 should disappear because mouse leaves. This is not correct, so we implemented a mouse popup stack and keep parent visible when child still having mouse inside.
Caution: never forget to unregister mouse leave binding before elements disconnected.
