Ghast Can Move Even With {NoAI:1b} tag

I'm Re-looking The Ghast Texture When I Was Trying To Get Inspiration For Recourcepacking But I Decided To Kill It Afterwards

I Thought That It Was Suppose To Be Like The Other Mobs....
Usually, Other Mobs Don't Move When Hit If They Had {NoAI:1d} tag.

Steps to Reproduce
1. /summon Ghast ~ ~3 ~ {NoAI:1d,ActiveEffects:[{Id:11,Duration:1000000,Amplifier:1000000}]}
2. Hit It With Any Weapon
3. Should Glide Upwards A Few Blocks When Hit

Ok Thats All~ THX MOJANGSTARZ
