[webkit-dev] Stop animating dynamic content

[ARaj]

Hi All,
       Is there any way to stop animating dynamic content on a page?
For example, disable marquees, gif animations etc.
I tried using:
mainFrame->animation()->resumeAnimations(mainFrame->document());
mainFrame->animation()->suspendAnimations(mainFrame->document());
But then, the animation at
http://www.gifanimations.com/animation/MenuSelection/1/40 still plays
:(

Any help please.
