This test (does not save tokens across connections for favorites if asked to do so) flakes a lot in CI. I tried quite a few things here and it still flakes. The error is that the favourites button in the sidebar is stale the moment we click it.

But I've already removed all the caching we might be doing of the element. It now gets looked up and clicked immediately with no other steps in between. No idea how it can change that quickly. Assuming I'm reading the sequence of events and symptoms correctly.
