I noticed while redoing a project with XRI at work (from 2.5.3 to 3.0.5) that the ray interactor script does not allow anymore to scroll on a UI scroll view while having the pointer hover this specific scroll view. On the 2.5.3 XRI version it was working nicely but now in 3.0.5 it does work with the Near-Far Interactor and not with the Ray Interactor.
Here is a quick video example inside the XRI DemoScene where I have a Near-far interactor in my left hand and a ray interactor in the right one, both setted up with XRI Default Input Actions.
I made some research and could not find anything explaining. It is a known bug ? Is there a way to cleanly fix this without having to do a MonoBehavior script running on Update() on the ScrollRect component for overriding the interaction.
