The trap gate alone could not restore capture: update_hovered_object picks the nearest geometry, then applies the mouseover-eligibility gate to that single winner. Arathi Basin's visual-only aura GameObjects (180102, type 6 TRAP) sit at the node banner's centre, so once the aura is correctly ineligible the pick returned nothing and the banner behind it was unreachable -- no cursor on any node, neutral included.
Cast for every hit nearest-first and take the first the eligibility gate will publish, in both the exact and halo passes, so an ineligible front object no longer buries an interactable one behind it. The final publish gate now reuses the same predicate.
