2.4: "Can't perform a React state update on an unmounted component" warnings

[webbedspace]

These warnings appear in the console during use. I can reproduce this by opening a passage editor (I used one that had the alpha Chapbook's toolbar) then closing it. Not sure how important these are or anything.

Twine version number

2.4.0-beta3

Does this problem occur with the web version of Twine or the desktop app?

Web

What operating system does this problem occur on?

I think it's tied to the Popper component used for these popups trying to do an update after the button is unmounted, but I'm not 100% sure. In my experience so far these warnings are good to clean up, but not showstoppers.
