Monsters and animals heads and bodies turn slowly after 90 degrees.

When monsters and turn the first 90  degrees it fine but anything over that they just start turning slowly.

To see this spawn any mob might be easy with a tamed wolf sitting then go behind so it can turn to look at you and it happens I've also got a recording of a tamed wolf turning slowly watch it to see. Hope we can get this fixed.
It is easy to see in creative mode.

What we are expecting to see

Monsters and animals head and bodies to turn the same speed 360 degrees after 90, not after 90 then turning there heads and bodies slowly.
