Cannot drag green line anywhere in model tree

Data needed for investigation. So a PTC case has been opened.

This is usually the case when another dashboard is (still) open.

Example: The Model Tree has limited functionality while a new feature (e.g. Extrude) is being created and the dashboard is waiting for user input and confirmation. After confirming, creating the new feature and closing the dashboard, the INSERT HERE bar can be moved again.
