All lines below should use the same serif font, with the word "weight" in italics:
<p id=test1>Using original family name of a FontFace</p>
<p id=test2>Using updated family name of a FontFace</p>
<p id=test3>Using updated <b>weight</b> descriptors</p>
<p id=test4>Using updated unicode-range descriptors</p>

</body>
