[MC-74113] /entitydata NoAI on Ender Dragon causes it to rapidly vibrate

To reproduce:
1) Summon an Ender Dragon.
2) Type

/entitydata @e[type=EnderDragon,c=1] {NoAI:1}

A very glitchy, rapidly vibrating Ender Dragon should result. This is likely caused by the way that the Ender Dragon turns. Relogging fixes the issue, but the Ender Dragon will be completely straight and always face North.

This does not occur with any other mob.

This seems to be closely related to my other report, MC-74114, since once this issue is fixed by relogging, the dragon no longer takes damage.

Confirmed for pre-4. Including a video demo. Seems to only affect Dragons that are not level when the command is issued.

Also this was discovered while testing MC-73719 🙂.

this is fixed in 15w31b, on my side at least

Still an issue in 15w36c (sorry haven't tested it lately).

Reopened.

....aaaand resolved:

If changing NBT via commands does not have the expected effect, that's always considered "working as intended".
