Auto-Stand from Prone Mechanic

Definitely see this happening when I am near a wall inside of a building.  I go prone, and then instantly I am standing again, and the cycle will repeat if I press prone again.  Seems the only way to deal with it is to move further away from the wall.  I think the distance they're using as the threshold to consider as a "too small for prone" position is a bit unrealistic because I am typically oriented in a way that I should be laying almost parallel to the wall itself.
