No Armour-bar shown.

My armour-bar isn't shown when I exit the Nether-Portal.
Normally, there will be a bar with a couple of "mini-chestplates", as you know what I'm talking about...
But if I exit the Nether-Portal AFTER travelling between the dimensions, I don't see the bar.

Steps to Reproduce:
1. Put armour on.
2. Travel to Nether/Overworld.
3. Exit portal.
4. You don't see the bar.
