lowest/rightmost/topmost/leftmostPosition all have a bug where a relatively positioned object inside an inline does not properly get accounted for.

The bug is here:

        for (RenderObject* c = firstChild(); c; c = c->nextSibling()) {
            if (!c->isFloatingOrPositioned() && !c->isText() && !c->isRenderInline())
                bottom = max(bottom, toRenderBox(c)->y() + c->lowestPosition(false));
        }

We just skip over inlines.  The above code should really only run when children aren't inline.  We should walk line boxes in the other case looking for RenderBoxes.

[Dave Hyatt]

Really we should just find a way to deal with relative positioned kids via the layer tree, so that we don't have to recur into kids at all.  The only reason we recur into immediate children is because of relative positioning.

This looks like it is fixed to me now. OK to close?
