Bug description

After a fresh install of NC AIO, I noticed that often, when the "Confirm your password" modal dialog pops up, after the password is entered successfully, the underlying action is carried out, but the dialog itself does not close, and stays with a rotating icon in the inactive "confirm" button.
The JS error reported is

Error: Your focus-trap must have at least one container with at least one tabbable node in it at all times
    at y (focus-trap.esm.js:410:13)

Tested on both Chrome and FF.

Steps to reproduce

1. set up NC AIO
2. create a few users, files, etc
3. carry out an action which require a password confirmation

The modal dialog to be closed

Additional info

No response

Start by reproducing the password-confirmation modal after an action in a fresh Nextcloud AIO installation, then inspect the reported focus-trap.esm.js error and the modal behavior. Done means the underlying action still completes and the confirmation dialog closes without leaving the confirm button spinning.
