Elytra flight animation does not seem rotated properly to other players perspective in multiplayer

Relates to MCPE-176172, the flight animation of one player is shown incorrectly to other player, mine’s through multiplayer, although the elytra wings opened and the head rotates, the player from other’s perspective is shown not rotating to an angle to represent flying with elytra.

Steps to reproduce:

1. Have both devices’ Minecraft opened

2. Enter a world on the first device, make sure the multiplayer is enabled

3. with another device, join the world the first device is hosting (can be a LAN)

4. Get an elytra from creative inventory or via command (/give @a elytra 1), “@a” means all players, so if you’re doing this to only the device you’re using, use “@s”

5. Get a firework rocket, this is optional

6. Enter glide mode and observe from other’s perspective.

Expected result:
Animation of player flying with elytra includes elytra wings open and rotates based of where the player is looking at. Like these images below:
First player POV:

Second player POV:

Actual Result:
Based of other’s perspective, on flight, only the elytra wing open and player head rotates, but the player itself is not rotated to represent them flying with elytra (or in other words players in other's perspective started stand flying). Like in the image below:
First player POV (looking at second player):

Please note it can still be reproduced with any other skin pack regardless it is affected by unlawful restriction or not, like one in MCPE-176172 and an image below.
