Illagers become passive when terrain obstructs their route to the village during a raid

Description:

During a raid, if the path to the village is blocked, the illagers will simply run around aimlessly in place. Even if the player approaches, attacks, or kills them, they won't fight back. This often happens when illagers spawn in ravines, walled villages, or even when the raid takes place near a igloo.

Steps to Reproduce the Issue:

1.Create a superflat world and find a village in creative mode.Change difficulty to hard.

2.Obtain a command block .Enter the command:”effect give @e[type=!player] minecraft:slowness 1 6 true”.Keep it open and loop.

3.Enter the commend:”effect give @p minecraft:bad_omen 30 0 true”,waiting the raid start.

4.Find the illagers and build walls surrounding them.

5.Destroy the command block on step 2.

6.Turn the mode to survival.

Expected Result:

Illager will attack the player.

Actually Result:

Illager do not attack the player,even they being attacked.
