That would be pressure in the opposite direction. What you are describing is downward pressure on the plastic, which would close the crack, not pry it apart. I think the crack is a weak spot in the design and happens when installing the bumper. The U-shape of the plastic is akin to pulling apart a Turkey wishbone until it breaks.
