Issue #1 - I don't see a way to edit the Advanced Scripts for a reference attribute widget such as a grid. The only Advanced Script option is for the form cell containing the widget.
If this is supposed to be the new place to enter Advanced Script for a widget in a reference attribute, it only has a place for an Init script versus V7 which accommodates Init & Render scripts.
Issue #2 - Scripts that I put in the form cell Advanced Scripts - Init Script are not firing. Even a simple console.log.
V8

V7
