Web: After removing a member from the channel they are actively viewing, redirected to channel is stuck on loading

Description

Environment: 5.22 community-daily and release (webapp Chrome, desktop 4.4 macOS)

Steps:
1) Turn the experimental sidebar feature on
2) As user A click on a channel A to open in main view
3) On a different browser, log in as User B and remove User A from channel A (the channel they are actively viewing)
4) As User A dismiss the popup notification `Removed from...`

Expected: User A is redirected to Reception/Town Square, channel loads in main view

Actual: The redirected channel (Reception) is stuck on loading. Verified the same loading screen was present, regardless of sidebar setting toggle being set to filter by unreads or not.
Verified when sidebar feature was set to off and user is removed, Reception channel loaded on redirect without any issues.
