Open Bug 1477934 Opened 4 years ago
Figure out a way to implement has
Children on tags
This used to be a synchronous check done through a cached hasTags API, but we can't do synchronous querying here. Thus, bug 1477930 broke the open glyph on the tags root. A possibility may be to pass hasChildren as an argument when we create a container, and then keep it up-to-date using notifications. This may even be cheaper for other cases, and it's usually easy to query for children when we query for the other container information.
