Double-sided geometry collision doesn't work when using physics set linear velocity. This does not occur when using floating pawn movement or character movement components.
Working as expected in 4.19 CL# 4033788
This also occurs on 4.19.3 CL 4033788
Found in 4.20 CL# 4302132 and 4.21 CL# 4348893
This is a regression
The pawn will move through the back of the plane but collide with the front.
The pawn would collide with the plane regardless of what face it hits
