Tracer Pulse LOS Clipping Issues

Geometry issues with the stairs by 1st point choke on Dorado, (Replay Code QKSQRG) at 3:51. My pulse lands behind the enemy Ashe, they walk RIGHT ON TOP of the pulse, it explodes, but they are unaffected.
It looks like the pulse clipped slightly through the corner to the left of the stairs?? I’ve had the same issue on 2nd point Eich also, seems like LOS checks for pulse don’t work when the pulse disappears under map geometry?
