Strider Nodding to Warped Fungus

When holding Warped Fungus or Warped Fungus on a Stick, Striders nod their heads up and down rapidly as they follow you, resulting in a "bobblehead" motion, due to how striders sway as they walk. This occurs whether they are oriented right-side-up, or are upside-down due to "Dinnerbone". This may be in relation to how mobs have been updated to correctly look at food.
