Describe the bug
After you click "Forget (destructive)" on a snapshot, the button is replaced with a disabled spinner. Problem is that other snapshots will also get the same button, so you can't forget any other snapshot until the previous (only) forgetting operation succeeds.

To Reproduce
Steps to reproduce the behavior:

1. Go to a snapshot
2. Click on Forget
3. Scroll down to another snaphot
4. See "Forget" button disabled

Expected behavior
Allow the user to queue forgetting multiple snapshots.
