Calling .html vs .text is different on FF vs IE

This is for jQuery 1.5.3:

I have a test page with a script block with an id of "demo-script-01"

The following shows the contents of that script block in IE7/Windows (7.0.5730) and Firefox 3 / Windows (3.0.5):

alert($("#demo-script-01").html());

The following works in FF but not IE:

alert($("#demo-script-01").text());

Thanks!
