This is also a parity issue, as you're able to do the jump from both sides on Java. Carpets are also affected by this.
Steps to reproduce:
Build a corner wall/fence like the one pictured above.
Place a trapdoor on top of the edge.
Try jumping over the wall/fence from both the interior angle and the exterior one.
Repeat the same process with a carpet.
Observed results:
The wall/fence can only be jumped over from the outside.
Expected results:
You should be able to jump over it from both sides.
