When right clicking an item frame with a map as the item floating without a block a PlayerInteractEvent with LEFT_CLICK_AIR is called in addition to the PlayerAnimationEvent and the arm animation shown.

This does not occur in 1.14.x. However, if it is a new addition and not a bug at least the LEFT_CLICK_AIR is a bug and should be a right click. If that is the case, I would also suggest adding some way of knowing whether the PlayerAnimationEvent is right or left click.

I only tested when right clicking an item frame with a map, but this may occur with other entity types as well; I'm unsure.
