When looking at the generated iframe for a .cke_panel_frame instance's contents, there is no distinguishing class/id that is unique and consistent which I might take advantage of.
Specifically, I'm looking to append a class or id to the html or body tag
but looking through the contents of `this`, `parentDiv`, etc... available to me within that getHolderElement method, I can't seem to find a way to get access to something like the plugin/panel title, allowing me to convert "Font Name" to some "font-name" class.
Any thoughts as to how I might be able to achieve something like this?
