Crossbow if loaded is not shown when in off hand

What I expected to happen was...:

to see the crossbow take up both hands

What actually happened was...:
the crossbow did not show leaving the rocket in hand

Steps to Reproduce:
1. grab a loaded crossbow(mine had rockets)
2. grab other item in offhand
3. hit F to switch and watch the loaded crossbow disapeer in first person.(still appears in 3rd)
