Such descendants should not be contained by the fieldset because they
should be scrolled together with the fieldset contents. This CL adds
|position: relative| to the anonymous fieldset content box if the
fieldset can contain absolute-positioned objects.We need to add a special handling for OOF descendants of a LEGEND to
LayoutObject::ContainerForAbsolutePosition() because such OOF
descendants are contained by the fieldset in an NG fragment tree.
Without this change, we had some CHECK failures.Bug: 1153042
