+// The tags-intersection route is exactly the same as the tags-show route, but the wildcard at the
+// end of the route (*additional_tags) will cause a match when query parameters are present,
+// breaking all other tags-show routes. Ember thinks the query params are addition tags and should
+// be handled by the intersection logic. Defining tags-intersection as something separate avoids
+// that confusion.
