Boat Rotation Command Issue

The Bug

I wanted to change the rotation of a boat with a /data merge... command, but if the boat has a motion it doesn't rotate to the right rotation (It rotates a little before it stops). But if you check the rotation with a /data get... command it shows the right rotation (see attachments).

If the boat has no motion it almost always works correctly.

Thanks in advance!

 

How to reproduce:

 1) Place a boat

2) Give it motion with /execute as @e[type=minecraft:boat] run data merge entity @s {Motion:[0.01,0.0,0.0]} in a repeat command block

3) Chanche the rotation with /execute as @e[type=minecraft:boat] run data merge entity @s {Rotation:[45.0f,0.0f]}
