Signals Notebook: Number of External notifications can vary depending on material library type

Description

When external push notifications are enabled for Material Edit Events, editing an asset in a Compounds-type library triggers both asset and batch edit notifications, while editing in Custom or other non-structure libraries triggers only asset notifications. 

This occurs because compound libraries update linked batch properties (e.g., structure-derived fields), generating batch edit events. This is by design.

Expected behavior

To understand and manage notifications:

• Expect multiple notifications (asset and one per batch) when editing assets in Compounds libraries due to linked structure properties updating at both levels.
• Expect a single asset notification when editing assets in Custom or non-structure libraries (e.g., Cell Lines) because batch-linked properties are not updated.
