When a slime block is pushed out by a piston, it cancels the original momentum of the entity it pushes out

Can you please provide a video on how to reproduce?

Can confirm.

Steps to reproduce:

1. Load the attached mcworld.

2. Pull the lever.

3. Load the Java world attached to the zip file.

4. Compare the trajectories between both editions.

Observed results:
In bedrock, entities won't maintain their momentum when pushed sideways using pistons and slime blocks.

Expected results:
Like in Java, entities should keep their momentum when pushed sideways and be flung diagonally when using the above configuration.

This also affects 1.21.20.0.
