Comment (by azaozz):

 This is also defined in TinyMCE's Schema class:
 http://core.trac.wordpress.org/browser/trunk/wp-includes/js/tinymce/wp-
 tinymce-schema.js#L705

 Also replacing <i> with <em> and <b> with <strong> is affected by the
 schema. In 'html5' they are not replaced:
 http://core.trac.wordpress.org/browser/trunk/wp-includes/js/tinymce/wp-
 tinymce-schema.js#L694

 The elements listed for removal when empty
 `'ol,ul,sub,sup,blockquote,span,font,a,table,tbody,tr,strong,em,b,i'` will
 not be removed if they have an id or name attribute:
 https://github.com/tinymce/tinymce/blob/master/jscripts/tiny_mce/classes/html/DomParser.js#L516

 So we have couple of options: edit the "remove when empty" list in the
 Schema class and/or extend the DomParser class to not remove these
 elements when they have any attribute (both would be good to submit for
 merging upstream).
