Ender dragon fly in circles after shooting projectile at her and never comes down to the portal

The bug

When entering the end, the dragon works normally as it should, but the fight is not the same as before.

To reproduce the bug:

1: Destroy all of the end crystals (with some end crystals left by, the ender dragon works normally)

2: Once all end crystals destroyed, shoot at her with a projectile. (Could be arrows from bow/crossbow, trident)

3: After she gets hit, it will appear to fly in a circle and never come down to the portal for its fire attack. (And it also appears to only fly upwards very slowly, making it kind of impossible to shoot it with arrows and killing it).

 

Note: This bug might be related to (MC-147221) but maybe not enough information, except for the video attachment I guess.
