Bug 1365472 - Use animated class names when doing selector matching in Servo; r=heycam Using SVG SMIL it is possible to animate the class attribute of an element using markup such as the following: <style> .red { fill: red; } </style> <svg> <circle cx="50" cy="50" r="30" fill="blue"> <set attributeName="class" to="red" begin="1s"/> </circle> </svg> In Gecko, Element::GetClasses handles this case by looking for an animated class string when the element in question is an SVG element. This patch causes our Servo bindings to use GetClasses when querying attribute values for selector matching. Note that animating the class attribute is *not* expected to affect attribute selectors such as `circle[class="red"]`. It does in Chrome, but that is due to a Blink bug where animating attributes using SMIL affects the result of getAttribute: https://bugs.chromium.org/p/chromium/issues/detail?id=735820 This patch adjusts the behavior for both the GeckoElement case and the ServoElementSnapshot case.
