@Shauny just confirming this is all about the “floating chat” window, none of this happens full screen.
I feel like the fundamental issue here @lindsey is that we are allowing chat in floating mode to even be involved with web page history. I think that if it is in floating mode it should get out of the way … we can remember “where it last was” when opening, but the URL switching we do in floating mode causes a lot of confusion.
