[IntersectionObserver] Handle hit test of inline targets correctly

If a target element is inline, then the hit testing code traverses
through the line box tree of the containing LayoutBlockFlow, which
won't check the stop node set on the HitTestRequest.

If the hit test result is an inline element inside the target node,
that should be treated the same as hitting the target node.
