I wanted to get a donkey to carry some items for me. When I found one, I tried to feed it carrots so it will be easier to tame. The feed button showed up, but when i clicked on it, it did nothing. When I tamed it, I couldn't open the donkey menu while sitting on it. I got off and crouched, and opened the menu to put the saddle on. When I closed out, the saddle disappeared. I opened and closed the menu again, and it reappeared. I attached a chest, but I couldnt access it by opening the menu.

Recreate:
Spawn Donkey
Try to feed it
Tame it
Try to open menu while sitting on it (The button dosent show up)
Get off
equip a saddle by crouching
equip a chest
open donkey menu
No chest area!!!! who's going to carry all my seeds??
