To elaborate:
- All my data layers are set with Initial Runtime State = Unloaded.
- In v35.20 this was working fine - only data layers that were manually loaded is visible.
- After the v36.00 update - multiple data layers appear intially loaded as seen in the video.
- Republishing the same island version fixed the issue.
So the statement was an assumption I made from what I observed, where it appears the update may have causes the Initial Runtime State = Loaded in the published island.
