    Comes back to a fix that landed in pre.5 which made the behavior in the editor and player consistent such that in both cases, AddComponent<InputSystemUIInputModule>() results in a blank UI input module without any connected actions. AssignDefaultActions() had to be called to put a default set in place.

    We are tweaking this behavior for 1.1 final such that if an InputSystemUIInputModule is enabled without any actions, it assigns a default set implicitly.
