IE10 beta errors on document.namespaces.add

[dpvc]

IE10 preview (in standards mode) throws an error when document.namespaces.add() is performed in MathJax.js. This code was to avoid a similar bug in IE9. Don't know if this will persist in the final release version of IE.

I can put the entire namespaces process within a try {...} catch(err) {...} command, and that would prevent the crash, but I haven't checked whether it works with MathPlayer or not.

==> QA testcase wanted

That does not seem really clear to me right now, so let's wait that IE10 is released before writing a test.

The test in this case is does MathJax actually run at all, as the namespace reference is part of the startup in MathJax.js so the error is thrown in IE10 just by loading MathJax.

OK, in that case I don't really need to write something for this since any page in the test suite will verify the bug.

Davide: I let you doing the testing for this too.
