When is the animation tooltip callback called?

I’m testing the animation callback on tooltip in order to create the animation options at runtime (at chart level):

 options: {
      responsive: true,
      tooltips: {
          animation: function(ctx){
             console.log("tooltips", ctx);
           }
      }
}

It seems that the function is never called.

Here is codepen: https://codepen.io/stockinail/pen/MWyWJxR

I don’t know if it’s a bug or I’m making any mistakes.

Looks like tooltip animation is not scriptable.

This was most likely fixed in beta.11

Yes, for this reason I have closed it! Now I have to implement tooltip animation config in my lib because I had put it on hold. I’m implementing new animation configuration. Sometimes I review my still open issues and to close them if outdated or if I have the answer/solution that at the creation time I didn’t.
