The fix to MCPE-113321 in 1.17.0 is not complete. Rabbits do eat carrots now, but only once in several minutes.
Steps to reproduce
Make a carrot garden inside a small fenced area.
Spawn a rabbit.
Expected result
The rabbit eats the carrots reliably and with reasonable regularity, with a short time between raids.
Observed result
The rabbit rarely eats carrots, sometimes only once in 5 minutes as shown in the attached video.
Technical note
Rabbits' raid_garden behavior has a priority of 5. By comparison, look_at_player has a priority of 11. However, they look at the player probably 20x more often than they raid a carrot plant. Likewise, random_stroll has a priority of 6, but they do that much more often than raid_garden.
As of version 1.19.50, rabbits appear to take no interest in planted carrots anymore at all.
Attached is a rabbit farm which used to work up until the release of 1.19.50, but doesn't work anymore since.
The coordinates for the farm's AFK point are X=23, Y=90, Z=24.
An older version of the same farm can be seen working here:
