Role checkboxes appear twice on user edit form - one set does not work

Can confirm the issue. I have created a patch to fix this.

I did notice that now the Admin user can no longer change roles via the USer Edit screen.
That was not a big problem because it was still possible via the 'Roles' tab, but I fixed it anyway in a new patch.

I'm not able to reproduce this. Could you please try in a vanilla Drupal environment?
