@MikeyMJCO @eileen this seems like a bug with CRM_Contact_BAO_Group::getGroupsHierarchy() where if a spacer (added before a child group title to distinguish the group as a child group) got an HTML tag then its been rendered as a raw text. I can replicate this bug in other places where this fn is been used adding hierarchical group widget. Like on 'Find Contact' search form:
@monish.deb I don't really know this code & I think I won't recover quickly from taking a quick look.... That fix seems similar to other places in the code & if it doesn't have side effects it would be good to get a quick fix out
