Scroller doesn't drag when far from Origin

[marc-antoine-girard]

I have an XR rig with a worldspace UI in my scene. The UI's root has a parent with a unified scale of 0.001F. The scroller works as expected. When I move them at around (5000, 0, 0), I can't drag the scroll anymore. I can still interact with the elements in it, but click and dragging doesn't work.

Setting the Drag Threshold to 0 on the scroller makes the drag work again, but a can't click on any elements in it. A value of 0.001F "works", so it seems that the Drag Threshold is linked to the UI's world position?
