Review Comment:
> I think some of the logic might read better if there were fewer negations.
I inverted this boolean in a new commit.
> Also, what happens if these are the same, but both are null?
The banner will be hidden when `managerState === null` is checked.
> What happens if `getManager()` errors?
We don't have much error handling anywhere in the monitor code but I could
add a catch block in this case to `console.error` the error.
