Llamas have abnormal detection range for wolves

Llamas have abnormal detection range for wolves in 1.21.4

They won't spit (or see the wolves) to the wolves in 1.21.4 in a distance. However, in the same distance, the llamas can spit to wolves (or see the wolves) in 1.21.1

Here are two videos that show the glitch.
