I am trying to use the hoverIntent.js with Raphaël.js at This Demo to handle the handlerIn function not immediately and waits until the user's mouse slows down enough before making the call of any function( like Hover) but I am getting this error:

Uncaught TypeError: Failed to execute 'animate' on 'Element': The provided value is not of type '(AnimationEffect or sequence<Dictionary>)'

Can you please let me know why this is happening? and does Raphaël.js has any built in function to do the same job?
