Steps to reproduce

1. Build a sticky-piston-and-pressure-plate powered door/wall as shown in the video.
2. Stand on the pressure plate to extend the sticky pistons.
3. Walk from the pressure plate into the piston arms and keep trying to walk through them.

Expected result

You can’t walk into the piston arm or you get pushed back out the way you came when it retracts.

Observed result

When the piston retracts you walk through the space where the piston arm was, where the block is retracted to.

If i go to a piston that is extended then if i stand in the piston arm then if i wait to it retracts then i get glitched into the block that piston has extended and then i can go through the block that it has extended.
