The bug
Retracting pistons push entities which are directly behind the piston base back a little bit, this can be seen in
[media]. As the entity is not visibly intersecting with the retracting piston, there should be no reason why the entity is moved.
How to reproduce
Place for example a sideways facing piston
Stand directly behind the piston base
Power and unpower the piston
→ You should be pushed by the piston

This seems to affect pistons rotated in all directions, therefor I am going to make the report more generic, I hope you are fine with that.

Thank you for further looking in to that. I'm completely fine with the changes as well.
