 A class attributed is listed as supported in the
 [http://codex.wordpress.org/Caption_Shortcode Codex] and it looks like
 support was added in this [https://core.trac.wordpress.org/changeset/27404
 Changeset]. But, if I add one manually in text view, and switch back to
 the visual editor, the attribute is stripped.

 Unfortunately, I'm not familiar enough with the WP internal javascript to
 pinpoint exactly where this is happening.
