How to hide fields according to the role of the user?

Am also facing the same problem when using the Conditional fields with the User account form. After some debugging, I found the reason the Roles, Name, and Email fields are part of the field parent account associate array coming from the core.

Remaining task:
The patch still needs some work to populate the selected value and testing.

Initial patch for resolve parent fields.

Testing patch - widget now correctly shows fields, but the values aren't retained when hitting save.

Example - set Roles as dependency
1. Select a few roles in the widget
2. Hit save
3. Edit the same condition
4. Previously selected roles are still unchecked

I'm changing this to Major, as it affects core functionality.

The workaround I had to do was to create a new role placeholder field as entity reference to roles, hide the original field, and fill the original one in the form submit hook. Presave could work too.

Then I used the new role placeholder field with conditional logic to make things work.
