pillagers maintain visual contact, but do not react to the player within the proper detection and attack radius

While playing on version 1.20.4 I discovered a strange feature in the behavior of these mobs. They did not take their eyes off the player model, but did not attack or come closer, as if they were frozen, only by getting too close I was able to attract their attention. I previously saw this in this version of the game, but did not pay specific attention to it
