Portal 2 Coop - impossible to progress on mp_coop_tbeam_end (funnel is bugged)

[tifgor]

On map mp_coop_tbeam_end (last map on course 4) the funnel should clip through the hole in the wall, but instead it is blocked by the wallframes. Making it impossible to progress further and complete co-op.

Bug shown in picture (as well as comparison to how it was)

I presume the bug appeared since some update and the map was not tested since, because it was fine when I played it last time before that, in April 2021. Must be a mapping issue

Tried replacing the portal, didn't help. Also tried reloading the map in co-op, and trying it in singleplayer - the issue stayed.
