Bees have a northwest wandering bias

This essentially clones MC-166980. per comment

The bug

Bees have a tendency to pathfind towards the north-west. So far, I have tested this only for bees spawned using /summon: YouTube video

This issue seems to have persisted, according to this comment for 1.16.1, information from MC-206396 in 1.16.4 (although the game is modified), and having tested it myself. I cannot say if it is less or more biased than it was before 20w12a/20w22a.

An easy way to reproduce this would be to spawn them in at 0,0 and watch where they go after a few minutes, but one can also perform a /kill command with xyz/dxdydz values to count the bees in each quadrant. This yielded ~6 times as many bees in the northwest quadrant than each other quadrant individually, after ~5 minutes of waiting.
