i'm using addCSS() to change the background color of an editor:
CKEDITOR.addCss( 'body { background-color: gray; }' );
That works great. But I'm worried that if this is used repeatedly within one browser session that the styles will accumulate, taking up memory or degrading the time it takes to instantiate a new editor. Or maybe it just seems messy. So is there a counterpart method to remove the css that was added using addCSS(), without touching the other CSS contained in the configuration?
