Base movement speed of piglins has gotten much slower

The bug

I notice that the movement speed of the piglins has gotten much slower compared to previous snapshots. This make piglins (especially the ones with crossbows) way too easy to kill due to their slow movement speed. You can observe their movement speed of how slow they pathfind.

I suspect that there was something to do with the generic.movementSpeed that causes the piglins to become slow. Apparently it IS the movement speed attribute that set the base to 0.3499999940395355, but in the previous snapshots, they were set to 0.5 (which was their original default speed).

How to reproduce

1. Spawn piglin

2. Do F3 + I

3. Find the generic.movementSpeed attribute
   → ❌ The base of the attribute is 0.3499999940395355 (or a random value) rather than being set to 0.5.
