>+        Layout Test svg/dom/animated-tearoff-list-remove-target.html is a flaky timeout

>+        The test is flaky because we get the animVal.getItem(0) of the 'x' attribute
>+        from the target element without initializing this attribute with a base value.
>+
>+        The test assumes the animator would set the animVal of the 'x' attribute
>+        from the 'from' attribute of the <animate> element before animVal.getItem(0)
>+        is executed. But this may not always happen. Therefore the test will get 
>+        the 'IndexSizeError' exception and it will time out.
>+
>+        The fix is:
>+        -- Initialize the attribute of the target element by a base value.
>+        -- Use requestAnimationFrame() instead of using setTimeout() to make the
>+           test deterministic.
>+        -- Allow the animation to advance one more step after kicking off the GC
>+           to ensure the variable 'animItem' is detached from animVal.getItem(0).
