[BUG] long pressing Posts when currently in messages bugs out the header and nav bar

[andysteakfries]

Describe the bug
Long pressing Posts when not currently in that part of the app. The header and content window changes to default feed, but the navbar still shows the Inbox icon highlighted.
Navigating using the Subs menu to a different feed, the header continues to display the name of default feed.
Similar bugs occur when long pressing Inbox when I'm a different part of the app.
There's also some frame rate drops that may be related to this bug.

To Reproduce
Steps to reproduce the behavior:

1. Tap "inbox"
2. Long press "Posts" (nav bar should now be bugged)
3. Tap "Subs" (header should now be bugged)

Expected behavior
Normal stuff happening
