Sub-groups display incorrectly when editing contact Tags & Groups section
Top-level groups appear correctly in the Groups pane when editing the Tags & Groups section for a contact. Sub-groups appear surrounded by a tag. See attached screen grab. The same tag is visible (for subgroups) in the Group pull-down menue for selecting a group.
This error has been seen in 5.30.0 (WP) and 5.29.0 (Joomla), so I'm guessing it's a core issue.
