Ender Dragon Facing Direction Uses Tail Instead of Head

Description:
The facing direction of the Ender Dragon appears to be based on its tail rather than its head. This leads to inconsistent and unintuitive behavior when using commands that rely on entity facing direction.

Steps to Reproduce:

1. Summon or locate an Ender Dragon.

2. Run the command:
   /tp @s ~ ~ ~ facing entity @e[type=ender_dragon,limit=1]

3. Observe the direction the player is facing.

4. Additionally, run:
   /execute at @e[type=ender_dragon,limit=1] run setblock ^ ^ ^10 stone

5. Observe where the block is placed relative to the dragon.

Expected Result:
The facing direction should align with the Ender Dragon’s head (where it is looking).

Actual Result:
The facing direction aligns with the Ender Dragon’s tail, causing commands using facing or local coordinates (^ ^ ^) to behave incorrectly.

Impact:
This makes it difficult to use the Ender Dragon reliably in datapacks, maps, or command-based systems that depend on accurate facing direction.

In the video, summon NoAI:1b is used to make the bug easier to demonstrate visually. In fact, even without this tag, the facing direction is still based on the tail.

Suggested Fix:
Update the Ender Dragon’s facing direction to match its head orientation instead of its tail.

Additional Notes:
This issue can be consistently reproduced using both tp facing entity and local coordinate-based commands like setblock ^ ^ ^.
