Opening a notification doesn't change user properly

If I open an Android notification from Connect it opens as expected, but I’m still showing as being the previous user/account. If I reply it’s showing the user of the notification (as expected), but come out of that and it still looks like I’m in the previous account.

It would be useful to have an “open as…” option on posts, to switch user and open the post as that other user. When I get a notification I often don’t want to reply as the same user (for context; I get notifications that people have replied to my bots, which I don’t want to reply to from that account)
