> Source/WebCore:
> 
> SVGImage::resetAnimation() incorrectly started animations which could cause a crash
> when leaving the page. This patch fixes resetAnimation to only stop the animation,
> similar to BitmapImage::resetAnimation().
> 
> Additionally, this patch removes an unneeded call to Document::updateStyleForAllDocuments()
> that was present in the animation loop. This makes the animation code more resistant to
> similar bugs in the future.
> 
> Both of these changes are functionally covered with existing tests.
