The Bug:

When trying to target the dragon using it's UUID in a command, the sub-hitboxes will be targeted instead.

Steps to Reproduce:

1. Place down the following command block:

   /give @p repeating_command_block{BlockEntityTag:{Command:"/tp @e[type=minecraft:ender_dragon] ~ ~5 ~ facing 0 0 0"}} 1
   

1. Summon an ender dragon (Silent for ease of testing):

   /summon minecraft:ender_dragon ~ ~ ~ {Silent:1b}
   

1. Position the player very near to dragon, look at it.
2. Try and run one of the following commands on the dragon using it's UUID as the target:

   /kill
   

   or

   /data get entity 
   

Observed Results:

The commands will target the dragon's sub-hitboxes, and will not be able to execute the command properly.

Expected Results:

The commands would not target the sub-hitboxes, but instead the dragon entity as a whole.
