Survivor Woodie's beard has a bald spot

The one area of Woodie's beard on his Survivor skin reveals a bald spot under his main head sprite, since the default idle animation has the player model bob up and down, thus revealing this "bald spot" under his mouth sprite. The Guest of Honor skin avoids this problem by having the main head sprite colored orange right where his beard/mouth sprite rests. This has been bothersome for quite some time now and I hope this can be updated. (Pics for reference)
