When opening Shulker Boxes the chest lid pushes players too far. Pushes players up 0.5 blocks, but 1.1 block horizontally.

Can confirm this behavior in 21w43a. Here are some extra details regarding this problem.
The Bug:
Shulker boxes push players much further horizontally than vertically.
Steps to Reproduce:
Enable the F3 debug menu so that your coordinates are visible.
Summon a shulker box that's facing horizontally.
Stand as close as you possibly can to it by running the following command.
Take note of the value of your "X" coordinate, open the shulker box and wait until it stops pushing you.
Close the shulker box, and compare the value of what your "X" coordinate is now, compared to what it previously was. (If done correctly, you should have been pushed exactly 1.1 blocks horizontally).
Place down a shulker box facing upwards and stand on top of it.
Take note of the value of your "Y" coordinate, open the shulker box, and wait until it stops pushing you.
Compare the value of what your "Y" coordinate is now, compared to what it previously was. (If done correctly, you should have been pushed exactly 0.5 blocks upwards).
Observed Behavior:
Shulker boxes push players much further horizontally than vertically.
Expected Behavior:
Shulker boxes would push players the same distance horizontally and vertically.
