Bow is held upside down in 3rd person

In 1st person bow appears normal while pulling it back (dark grey pixel is on the bottom of the arrow tip), while in third person the dark grey pixel is ontop of the arrow tip. With a texture pack it's noticable even if the bow isn't pulled back. In the example below I've made a simple texture pack with just the bow texture changed (with a red pixel on the top part of the bow).
