jQuery replace html in span
<p>Is there an issue with replacing the contents of a <code>&lt;span</code> in jQuery.</p>

<p>I have this;</p>

<pre><code>&lt;span class='DimensionList'&gt;
  some html
&lt;/span&gt;
</code></pre>

<p>and </p>

<pre><code>$('.DimensionList').html("&lt;b&gt;This is the new html&lt;/b&gt;");
</code></pre>

<p>What I'm finding is that in FF the contents of the span are being added to.  So the new HTML sits above the old.</p>

<p>In IE6, yes I have to cater for it, it's doing much the same.</p>

<p><strong>EDIT</strong></p>

<p>I have edited the question to show that there is html in the replacement html</p>
