This was basically triggered by this forum post: https://forum.backdropcms.org/forum/how-set-selected-tag-form-select-opt...
As it is currently, you cannot easily add attributes to individual options of select elements, and it requires either a lot of theming work, or to port a module like https://www.drupal.org/project/form_options_attributes. Even with that module, things are not consistent, so we should consider backporting the D8 solution being worked in https://www.drupal.org/node/342316

Does the Administrator role of your site have the permission "Access administration bar"? (I think, you wouldn't notice the missing permission if your own account is the so called User 1.)
