This is the same issue reported in MCPE-107675. The 1.19.40 changelog seems to report that the issue was fixed when it states:

• Fixed a problem with teleports appearing to fly the target to the new location instead of being instant

However, in the current version entities visually move through space when teleported instead of instantly disappearing from one location and appearing at the target location. I believe this behavior has never changed since 1.16.100, and the statement in the 1.19.40 changelog either was not accurate or referred to something else.

Steps to reproduce

1. Set up an impulse command block with the command /execute as @e[type = armor_stand] run tp @s ~5 ~ ~
2. Place an armor stand.
3. Place a button on the command block and press it.
4. Spawn an enderman and watch it.

Expected results

Teleporting should appear to be instant. The armor stand and the enderman should visually change position instantly when they teleport.

Observed results

The armor stand and the enderman appear to be moving through space when they teleport. Their movement is animated like a natural movement.
