<title>Test that invalidation takes filters on ancestors into account</title>
<desc>
This test checks that when a container element changes, the area of
the screen that is invalidated and repainted takes account of any
filter effects on the ancestors of the changed element.

{
document.getElementById("g").setAttribute("opacity", "1");
document.documentElement.removeAttribute("class");
