Arathi Basin's visual-only aura GameObjects (entry 180102, type 6 TRAP) were offered inside a battleground because the whole shared gate was skipped, so they won the pick over the node banner and the CMSG_GAMEOBJ_USE landed on a no-op trap (the server only played its despawn anim). The TRAP inverse is not a team marker, so it still gates: a friendly or neutral aura trap stays at priority 0, the banner (BUTTON/GOOBER/CHEST) wins, and a neutral node captures.
