<pre>SMIL animations inside SVG image do not get paused in background tabs.
Example:
<a href="https://pr.gg/svgExamples/smilAnimationImage.html">https://pr.gg/svgExamples/smilAnimationImage.html</a> (first animation)
The issue is that SVGImage has its own Page object (SVGImage::m_page) and this page contains the SMIL animation (not the main page). When the tab goes into the background, the main Page knows it is no longer visible and it pauses its SVG animations. However, the Page inside the SVGImage does not currently know it is no longer visible and its SVG animations keep going.
I saw this issue on Yahoo News and reduced it.</pre>
