Occurs on 1.21.8-DEV-ver/1.21.8@612d9bd with a minimal plugin list:

[17:54:21 INFO]: ℹ Server Plugins (11):
[17:54:21 INFO]: Paper Plugins (3):
[17:54:21 INFO]:  - BlueSlimeCore, FancyHolograms, MiniPlaceholders

Notably also only occured to us with Happy Ghasts. From looking at the code, I'm guessing happy ghasts move too quickly

@Override
    public void travel(Vec3 travelVector) {
        float f = (float)this.getAttributeValue(Attributes.FLYING_SPEED) * 5.0F / 3.0F;
        this.travelFlying(travelVector, f, f, f);
    }

The hitbox in which to look for entities to collide with is resized to be big enough to fit the travelVector, but this ends up being outside of the Region ticking that Ghast. However it appears to me it would require Absurdly high speeds for the hitboxes to expand this rapidly, in the provided logs it expands by ~1000 blocks on one axis, on our server it ended up being even more than that.
