Fix position of layer with floating ancestor within inline parent layer

Fix position of layer with floating ancestor within inline parent layer

<span style="position: relative">
  ...
    <div style="float: left">
      ...
        <target layer>
      ...
    </div>
  ...
</span>

Because of the floating ancestor, the containing layer of target layer
is not the span, but the layer found in the containing block chain.
