Armor slots not displaying correctly

I went to put on some armor in the latest snapshot, but something strange happened.

What I expected to happen was...:
I expected the armor to go into the appropriate slot with the correct armor symbol.

What actually happened was...:
My helmet went into the boots slot, my pants went into the chestplate slot, my chestplate went into the leggings slot and my boots went into the helmet slot.

Steps to Reproduce:
1. Equip armor (either by putting the armor in the slots mentioned above or right-clicking in the hotbar).
I believe the symbols indicating what armor slot a slot is have been accidentally reversed somehow.
