PDF Embed API: Annotations API, ANNOTATION_ADDED event not triggering for notes

Hello,

I am encountering an issue with the Annotations API. When adding a message to the document with the subtype "note," the ANNOTATION_ADDED event is not being triggered. It does work as expected for other subtypes such as "strikeout," "highlight," "underline," and "shape.". This was working fine a few days ago.

This issue can be tested with the Angular demo (/annotationAPIs/UIConfigurations). 

Here, you can observe two events (related to drawing and highlighting marks), but none for note-type marks:

Thanks!
