adjustedPositionRelativeTo() couldn't find offsetParent.

LayoutBoxModelObject::adjustedPositionRelativeTo() could get confused
by inline continuations, and could fail if offsetParent itself was a split
continuation.  If the child belongs to the second part of the continuation,
we'll instead race to the root of the tree.  By comparing with the node instead,
we correctly identify the offsetParent and stop the search.
