After the problem is solved, I have to use global variable to control whether the ui is mounted, like window.__mountedNames. I think the implement should going on under the hood.

Interesting, the ContentScriptContext should be causing the UI to be removed if the install/update events are firing and when if it sees another version of the same script is being executed.

I'll double check this at some point, but it's a low priority rn since you have a work-around.

There was a bug in the content script context, so this should be fixed by #683!
