or

Short Reproduction

1. Make a new Library
2. Visit the page at /library/{ID}/edit
3. Press Delete Button

What happens?

After pressing the delete button the user can see the confirmation dialog flashing up for only a second. The duration is so short that it is impossible to confirm the delete request.

What is expected?

Confirmation Dialog should stay open and allow the request to be submitted.

Context

• 1.0.1+git.68bc76bc / Debian
• Tested on FF (82.0.1) and Chrome (86.0.4240.183) with addons disabled.
• Not effectd by library containing content
• Not affected by library permission setting

Funkwhale version(s) affected: 1.0.1

Workaround

Deletion from /api/admin/music/library/ works as expected and is a valid workaround. Therefore, I'd categorise this as fairly low impact bug personally.
