Attempts to remove groups from Adminstrator role incorrectly fail with message "You can not remove a user/group that will result in completely removing yourself from this role"

I have a permission scheme that gives "jira-administrators" the administer project permission. If the jira-administrators gets added to the administrator role, I can't remove it because it says:

You can not remove a user/group that will result in completely removing yourself from this role.

I don't want the jira-admins as the administrator role because I also give this role the assignable user permission which isn't needed for jira-admins.

I have also seen this error when the project lead, who is not a "jira-administrator" member and is specifically listed in the Administrator role by userid, tries to remove the jira-administrator group from the role
