No "open" option on container on top of other open container

[Ostentatio 1,971]

I have a frying pan placed on top of a forge.

 

When the forge is open as a window, the frying pan's context menu shows "Close" instead of "Open", even if it is not open.

When the forge window is NOT open, the frying pan says "Open" as it should.

 

So, in effect, I can only open the frying pan to view contents if I do not have the forge open already; opening the frying pan first, then the forge, leaves both containers open and functional.
