    "Anonymous block boxes are ignored when resolving percentage values that would refer to it:
    the closest non-anonymous ancestor box is used instead."
    When figuring out whether auto height needs to be applied on the current box, ignore anonymous
    ancestors until the first non-anonymous containing block is found. This matches both
    Firefox and Opera behaviour.

    * rendering/RenderBoxModelObject.cpp:
    (WebCore::RenderBoxModelObject::hasAutoHeightOrContainingBlockWithAutoHeight): Switch from
    isAnonymousBlock() to isAnonymous() to make sure all anonymous boxes are ignored.
    Remove isTableCell() check which is a noop as table cell isn't an anonymous block.
