Signals Notebook: Permissions added to a notebook are not being cascaded to the contained experiments

Description: When adding a new user with full control permissions to a notebook, the permissions are not cascaded to the experiments in the notebook. Adding the previous user will not fix the issue. This happens because notebook-level permissions can not longer be cascade to experiments within the notebook if all previous users with access are removed at some point.

Solution: This is a known limitation of the application always add the new user before removing the old one from the notebook to maintain the ability to cascade permissions.
