Items used on mobs are not counted in statistics

The "times used" statistic for items does not reflect instances where the item is used (right click interaction) on a mob. This means that:

• Name Tags
• Leads
• Horse Armour
• Chests used on Donkeys, Mules and Llamas
• Carpets used on Llamas
• Any items used to breed animals

Are all uncounted in statistics. This seems inconsistent with the purpose of usage statistics, especially for Name Tags and Leads, where this is unequivocally their only use.
