Display entities that have interpolation duration greater than 0 will visually reset their transformation back to default when the player leaves and rejoins.

To Reproduce (Unexpected Case)

1. Ensure you are in spawn chunks
2. Create a display with interpolation duration 1

   /summon block_display ~ ~ ~ {block_state:{Name:"stone"},transformation:{translation:[1.0f,1.0f,0.0f],left_rotation:[0.2f,0.5f,0.0f,1.0f],scale:[2.0f,3.0f,9.0f],right_rotation:[0.0f,0.0f,0.4f,1.0f]},interpolation_start:-1,interpolation_duration:1}
   

3. Move a few blocks away
4. Create a display with interpolation duration 0

   /summon block_display ~ ~ ~ {block_state:{Name:"stone"},transformation:{translation:[1.0f,1.0f,0.0f],left_rotation:[0.2f,0.5f,0.0f,1.0f],scale:[2.0f,3.0f,9.0f],right_rotation:[0.0f,0.0f,0.4f,1.0f]},interpolation_start:-1,interpolation_duration:0}
   

5. Leave and rejoin the world
6. Notice the first display reset to the default transformation but the second one did not
7. Go to the first display and run

   /data get entity @e[type=block_display,sort=nearest,limit=1]
   

8. Notice the NBT is correctly stored. The issue is only visual.

To Reproduce (Expected Case)

1. Leave spawn chunks

   /tp ~100000 ~ ~
   

2. Create a display with interpolation duration 1

   /summon block_display ~ ~ ~ {block_state:{Name:"stone"},transformation:{translation:[1.0f,1.0f,0.0f],left_rotation:[0.2f,0.5f,0.0f,1.0f],scale:[2.0f,3.0f,9.0f],right_rotation:[0.0f,0.0f,0.4f,1.0f]},interpolation_start:-1,interpolation_duration:1}
   

3. Move a few blocks away
4. Create a display with interpolation duration 0

   /summon block_display ~ ~ ~ {block_state:{Name:"stone"},transformation:{translation:[1.0f,1.0f,0.0f],left_rotation:[0.2f,0.5f,0.0f,1.0f],scale:[2.0f,3.0f,9.0f],right_rotation:[0.0f,0.0f,0.4f,1.0f]},interpolation_start:-1,interpolation_duration:0}
   

5. Leave and rejoin the world
6. Notice both displays retain their transformation
