Resolution Note:
The system has been created not to keep the reference of the canvas when it’s disabled, even when the transform hierarchy is working.
In this case, it is best to check if a canvas is a root canvas manually by traversing the parents in the hierarchy. We agree that the documentation could be improved in that area and we will provide an example there in a near future.
