 I think this issue should probably be fixed upstream in TinyMCE itself - I
 have opened a pull request on github to add this  -
 https://github.com/tinymce/tinymce/pull/428

 In the mean time - heres a patch that fixes it.

 Note - I have also done this in the past by adding it to
 {{{valid_elements}}} using the {{{tiny_mce_before_init}}} filter, but I
 think it would be best to avoid doing this in core.
