isVisibleOnScreen overflowHidden method does not take into account position parents

[straker]

Take the following html

<div id="parent">
  <div class="container">
    <div id="target">Hello World</div>
  </div>
</div>

<style>
  #parent {
    overflow: hidden;
  }

  .container {
    position: absolute;
    top: 500px;
  }
</style>

Running axe.commons.dom.isVisibleOnScreen(target) returns false even though the text is clearly visible. This is because our overflowHidden method doesn't consider the positioned parent in between the target and the overflow: hidden ancestor that causes it to be able to break out of the overflow (it only looks at the positioning of the overflowed ancestor).
