Description

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

Steps to Reproduce
  1. Open attached project
  2. Play in editor
  3. Press W to move forward towards the plane

Results:
The pawn will move through the back of the plane but collide with the front.

Expected:
The pawn would collide with the plane regardless of what face it hits
