Attachment: A sample

Animation in below case is not shown up in devtools at all.

  var div = document.createElement("div");                                      
  div.setAttribute("id", "target");                                             
  div.animate({ transform: ['translateX(0px)', 'translateX(100px)' ]},          
              { duration: 2000 });                                              
  document.body.appendChild(div);

I guess we need to notify the animation to mutation observer somewhere.

I think we should do something in Element::BindToTree() with MayHaveAnimations() check.

I guess this is probably worth fixing eventually since it affects the reliability of our tools. Upgrading to P3.
