The disabled property is not being removed from the submit button on user profile frontend forms.
To reproduce this, trigger a validation error by attempting to submit a frontend user profile form with incorrect field value(s).
The submit button is properly disabled when clicking Submit (to avoid duplicate submissions) but the disabled property is never removed so it's impossible to re-submit the form after correcting the issue that triggered the validation error.
Frontend forms for posts are working correctly. It's only the user profile frontend forms that are experiencing this problem.
