"Back to Chat" button breaks if switching settings tab

When I first enter settings, the URL shows /settings/customization?rt=… and the button works.

As soon as I change the active tab (for example, going into ‘Account’), ?rt= disappears from the URL and thus ‘Back to Chat’ will now redirect me to a new chat.

I would expect ‘Back to Chat’ to work the same whether I enter another settings tab or not (i.e. always get me back to the chat I was using).

Easy fix, as it is probably just a matter of keeping the ?rt= on every navigation inside settings.
