Patch

The MathML user agent stylesheet has some 1px padding on the right/left of the &lt;math&gt; root. This was added a long time ago in

<a href="http://trac.webkit.org/changeset/61861/trunk/WebCore/css/mathml.css">http://trac.webkit.org/changeset/61861/trunk/WebCore/css/mathml.css</a>

but the intention is unclear, probably to tweak the spacing. I don't think that's necessary and it some tests have to revert this change to avoid 1px shifts, so let's remove it and keep the UA stylesheet minimal.</pre>
