+                Number of people having tried to fix this by z-indexing: 2
+                The problem arises from the following render order requirements:
+                - The stage menu must be rendered above the stage main.
+                - The stage main must be rendered above the action panel (because the monitor page must be rendered above the action panel).
+                - The action panel must be rendered above the expandable components drop-down.
+                However since the expandable components drop-downs are child elements of the stage menu,
+                they can't be rendered lower than elements that are lower than the stage menu.
+                Therefore we opted to forego the second requirement and hide the action panel instead when something obscures it (except the expandable components).
+                We assume that QQuickRectangles are always opaque and any other item is not.
