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

One way to fix this issue might be to just fix MCPE-179969.

Confirmed

Should I attach the same video that I used at MCPE-23544 that describes how an Enderman slide when moving?

Sure

Thank you for your report!
After consideration, the issue is being closed as Won't Fix.
Please note that this is not the same as Working as Intended, as this bug report correctly describes behavior in the game that might not be the intended or desirable behavior, but it will not be fixed right now. Sometimes, this is because the issue reported is minor and/or impossible to change without large architectural changes to the code base.
