MC-143186Summoning entities with motion that will collide with walls induces entity client-side position desync
The entity still follows the path it's supposed to make in server-side (I've tested it with setblocks @ its position), but the client-side gets desynchronized. It gets fixed when the entity touches the floor.
/summon minecraft:creeper ~ ~ ~ {Motion:[0.0d,3.0d,-9.0d]}
Run the command above with a wall and a hole in -Z direction (also works in all directions in the X-Z plane).
The bug could be affecting the Y axis too, but it's more difficult to appreciate (second 14 of the shorter video, the mobs don't reach the roof even when they should have collided with it).

Created Issue:
Summoning entities with Motion that will collide with walls induces entity cleint side Position desync
The entity still follows the path it's supposed to make in server-side (I've tested it with setblocks @ its position), but the client-side gets desynchronized. It gets fixed when the entity touches the floor.
/summon minecraft:creeper ~ ~ ~ {Motion:[0.0d,3.0d,-9.0d]}
with a wall and a hole in -Z direction.
but also works in all directions in the X-Z plane.
The bug doesn't affect the Y axis.

In version 19w11a I noticed that: if the summon command is executed in chat, the bug doesn't appears, but if the command is executed in a command block it still appears.
I'm not sure but maybe when Workflow changed from Global Mojang to Java, this bug's assigned priority got lost? Can't find it on Details.
Can't reproduce on 1.17.1 Pre-release 1
