What is the bug or the crash?

SensorThings data provider panel allows to select the following expand pattern (Datastreams -> Things -> Datastreams), which is inconsistent with the constraints enforced on the other entities that can not be expanded back on themselves.

Steps to reproduce the issue

Select Datastreams as base entity type, then expand to Things and back again to Datastreams.
