3564637 - No data previewed when Permissions Entity contains a DAC or protected view

When modelling a DAC, the Permission entity contains a DAC or a protected view in its lineage. 
In this scenario, no data is displayed. So DAC does not preview any data.

This is the intended behavior. Nested DAC are considered a bad modelling design.
Therefore, remove the DAC or Protected view from the lineage of a Permissions Entity.
