[jQuery] .append() into style element causes error in IE only

[Ant]

Hi,
I am trying to append css into a pre existing style element.
$("style").append(myClass);
This works as expected in Firefox, but not IE.
The HTML on the page validates to HTML strict, so I'm fairly sure that
it's not the issue with IE that append() won't work on incorrectly
written elements.
If I change my code to $("p").append(myClass); it works as expected.

Was just wondering if this is a know issue with IE or jQuery and if
anyone had a work around, I am out of ideas that don't involve
considerable effort :)

Thanks,
Ant
