Observables Strong Typing

[dennemark]

As mentioned in a discussion, this issue should keep track of adding stronger typings to observables.

Original discussion:

Is my assumption right, that observables are updated properly?

When writing it as property, it is missing proper typing though. Would this be easy to solve? Image shows typing when getting pointerDragBehaviour via create and the missing types when it is set as prop.
