[REQ] Preserve scroll state after adding people to groups

[Gabri3l]

Describe the problem that needs solving Any time I go on someone's profile from the main feed and add them to a group, if I hit back it brings me back to the top of the timeline instead of where I was before.

Describe the solution you'd like Ideally it would be nice to just resume from where you left off instead of being sent to the top of the timeline every time.
