[BUG] Character unseating from Talbuk mount

When riding the White War Talbuk as a Tauren, the character model does not seem properly "attached" to the mount. Mount-up animation puts the character to the right of the Talbuk, rather than seated correctly, and the character will pop back and forth between suspended in air to the right and being seated correctly while still. Also while running and jumping (forward or backwards) the character will bounce high in the air off of the saddle before back into the correctly seated position.

Tested Tauren's other mounts and was unable to reproduce, it is only occurring on the White War Talbuk as far as I am able to tell at this time.
