Goats won't drop their horns when ramming into solid blocks placed in front of the player

When a goat rams into a natural mountain block that is placed in front of the player (stone, iron ore, etc), it dosen't drop it's horn like it should.

How to replicate (may take a few tries):

• Spawn goats (the more goats, the less time it'll take)
• Give yourself a stack of stone, iron ore, copper ore, coal ore, logs, or packed ice
• Go into survival
• Stare at the ground, and wait until you hear a goat preparing to ram you
• Quickly pillar up two blocks. If done correctly, the goat should ram full force into the blocks you pillared up with

Expectation:
The goat's horn breaks off, giving you a horn.

Reality:
Nothing happens. No breaking sound effect is heard, and no horn drops.
