When riding pig, right-click action is done

Steps to reproduce :
1. Somehow spawn or summon a pig and saddle him
2. hold right-clickable item and try to ride pig.
3. you will ride pig, and also trigger the right click action (wearing armor, throwing projectiles, naming, writing a book, trying to fish a pig... etc)

Note : this does not happen on boat, horse, minecart.
