Functionality of Remove Case Role activity type is messed up
I think it's been like this for a few years. I can look into it later but recording here for reference. Examples of stuff below, and I can reproduce on dmaster.demo.
In the case roles section on manage case, click the trash can icon at the end of a row to remove a case role. It does remove the role, but there's supposed to be a Remove Case Role activity filed on the case.
In the Other Relationships section on manage case, add a new relationship. It gets correctly added but adds a Remove Case Role activity to the case. Besides being the wrong activity, no activity should be added here since that add button is just a shortcut to adding a regular relationship in the usual way, that exists outside of the life of the case.
