 * Make sure custom styles are correctly applied to TinyMCE editor.
 *
 * We use jQuery to wait for the document to be ready, and then we rely on a
 * little timeout to ensure TinyMCE is completely loaded before applying styles
 * to the content iframe. We do it via jQuery since iframes can't be efficiently
 * modified via linked or inline CSS.
 *
 * This function is pretty hacky, since neither WordPress nor TinyMCE offer
 * a simple way to apply styles dynamically to a TinyMCE box at the time.
 * Maybe in the future we could come up with a more elegant way to achieve this.
