Fix for [JDK-8257664][] – HTMLEditorKit: Wrong CSS relative font sizes.

_Disclaimer:_ I'm the reporter of the issue and I've been advised the best chance to get it addressed is to submit a pull request against this repository.  I haven't built the JDK myself, I'll need guidance if required.  I have a proof-of-concept example – demonstrating the bug and a workaround available as a [public gist](https://gist.github.com/stanio/b79ce9348946aa6b3395328ec4c59d14).  I have included a sample test though I don't know if it is annotated properly.

**Current behavior**

<style>
  h2, .h2 { font-size: 150% }
</style>

<body>

  <h2>Foo</h2>            

  <div class=h2>Bar</div> 

  <ol class=h2>           
    <li>Baz</li>          
  </ol>

  <table class=h2>
    <tr>
      <td>Qux</td>        
    </tr>
  </table>

</body>

**Expected behavior**

All text should be displayed with a font size of the computed `<body>` font-size × 1.5.
