After EZP-24994, if you click the "Universal Discovery Widget" to select a relation, the UDW will open in the "Default Location" defined in the class relation attribute.

The problem is, specially with cold cache or if the server is slow, the load of the tree if objects necessary to navigate to the defined location takes a long time.

It's important that this behavior is reviewed to optimize the loading speed both by means of UI/REST/Platform performance improvements (REST Embedding & other planned optimizations), but more importantly user needs to get a clue that UI is still working.
