User Agent: Mozilla/5.0 (Windows NT 5.1; rv:12.0) Gecko/20100101 Firefox/12.0
Build ID: 20120328051619
Steps to reproduce:
set .innerHTML of mathml element within HTML5 such as <mn> to change its content e.g.
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>mathml id test</title>
</head>
<body>
<p><math><mn id="o"><mn></math></p>
<script type="text/javascript">
document.getElementById('o').innerHTML=12;
</script>
</body>
</html>
Actual results:
blank page
Expected results:
should see a 12, or so I thought. http://www.w3.org/TR/2010/PR-MathML3-20100810/chapter2.html#id.2.1.5.1
specifies that mathml elements can have an id attribute. it does not say what you can DO with that attribute however. but I assumed that since mathml is part of HTML5, and SVG is part of HTML5, that I could use .innerHTML on those to modify their contents.

workaround for my web page:
...<mn><span id="o"></span><mn>...
this does not really fix the problem though.
and by the way, I don't think this is valid MATHML!

https://developer.mozilla.org/en/DOM:element.innerHTML links to
http://www.w3.org/TR/2008/WD-html5-20080610/dom.html#innerhtml0 which suggests innerHTML is only valid on HTMLElements.
But http://www.whatwg.org/specs/web-apps/current-work/#dom-innerhtml links to http://html5.org/specs/dom-parsing.html#innerhtml which says it's valid on all Elements.

For now, the simplest solution is to use DOM2 createTextNode and appendChild. Or set innerHTML on an HTML <p> that contains the entire MathML subtree.

you resolved my bug as a duplicate of someone else'e bug, and theirs is marked as a duplicate of https://bugzilla.mozilla.org/show_bug.cgi?id=811701
so, they say mine is totally unrelated to theirs. maybe you can unchain it or something. thanks.
