TYPO3 Core

When opening the "Directory Status" modal and having the message "These files or folders have errors and may be fixed automatically" the user can click the button "Try to fix file and folder permissions" and the errors get resolved.

In v12, the modal content is reloaded and the errors are fixed.
In v13, a progress bar is shown, but the action never completes. The user must close and reopen the modal to see that the errors have been fixed.

The browser console states:

Uncaught (in promise) TypeError: e.querySelector(...) is null
