Comment (by azaozz):

 TinyMCE uses "zero-width non-breaking space" characters to place the caret
 in DOM nodes and some other places. In version 3.4.5 (WP 3.3) only
 `\uFEFF` was used, however in version 3.4.9 (WP 3.4) `\u200B` is used
 instead of `\uFEFF` in Gecko. Unfortunately both are stripped from the
 content when the DOM is serialized.

 This code exists in TinyMCE latest too:
 https://github.com/tinymce/tinymce/blob/master/jscripts/tiny_mce/classes/dom/Serializer.js#L346

 The only thing we could do is to pass this upstream.
