Windows 1.6.8 Visual glitch - face removal and other sprite weirdness with emotes and interacting

Bit of a creepy one, perfect for the season: When you interrupt an animated emote (such as laugh, jar, sick, yes, etc) by attempting to interact with an object like a chair or chest, your avatar's face disappears. When trying to mount the horse in the same circumstance you can get even weirder results. In the case of a chair, when you click on it a second time, your face reappears and you sit in the chair as normal, except when you dismount you are still in the sitting position, hovering in the air.

Emotes where your sprite doesn't animate aren't affected.

I've confirmed this in vanilla, non-modded, and my girlfriend was able to reproduce it.

Some video examples:
