Summary
You know how the right side of the navbar has been blinky for a long time and we all kind of assumed it was a tricky extension thing?
blinky-nonsense.mp4
It was actually just a classic React "don't define a component within another component" issue.
This gets rid of all the visual glitching, unmounting/remounting, etc. shown above.
It also fixes https://openmrs.atlassian.net/browse/O3-2692 "Two errors on logout: person is undefined and Language ID should be string or object," which was caused by an extension within the user panel not getting unmounted when it should, which somehow was being caused by the erratic re-rendering behavior of the navbar, in which its slot was contained.
NB: Yes, this does indicate that there is a subtle bug in the extension system that can cause extensions to fail to be unmounted if there is a chaotic amount of churn. I haven't solved that. But hopefully we just don't have churn.
