Can't stop background from using my body style

I am using a custom stylesheet. The problem is that the stylesheet has its own body tag that is for the rest of the page but I don't want it applied to the CKEditor background. I've tried multiple things:

$config['bodyClass'] = 'mybody';
I set this class in my stylesheet, but it's being ignored

$config['bodyId'] = 'mybodycontent';
I also set this style id in my stylesheet but it's also ignored

$config['stylesheetParser_skipSelectors'] = ('/(^body|^\.)/i');
I believe this is supposed to cause it to not look at my body style but it still does anyway.

Any ideas?
