Lack of non-whitespace before initial equation causes problem in IE

[Stevenparsons]

It looks to me like there is a problem in IE if there is no non-whitespace character in the enclosing paragraph of the first MathJax equation in a document. I get the following:

User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; MathPlayer 2.20; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; InfoPath.3)
Timestamp: Tue, 2 Nov 2010 15:27:35 UTC
Message: 'parentNode' is null or not an object
Line: 35
Char: 3
Code: 0

Inserting a single character fixes the problem. See

for repro pages. Hard to believe, but it seems to have been there a long time. It also affects the main test/index.html page in the distribution. Can anyone else repro, or have I hacked into something somewhere that I've forgotten about that broke it for me?

Funny you should be posting that just as I posted the fix for it (see issue #13). It is the problem from SVN 621, which I fixed in my fork of MathJax. I would have checked it in myself long ago, but am trying to use the new production schedule, and I've only now figured out how it all works.

This is a duplicate of issue #13 so I'm closing it.
