 Currently, when a plugin adds a metabox with complex objects (like
 TinyMCE, Maps, CodeMirror etc) care must be taken to refresh the objects
 when the elements are moved (including hidden/shown).

 After some digging, I've found that this seems to works in most cases:
 {{{
 var context = "#custom_meta_box_id";
 $( '#adv-settings' ).on( 'click', context + '-hide, ', refresh );
 $( context ).on( 'click', '.hndle, .handlediv', refresh );

 $('.meta-box-sortables').bind( "sortstop", refresh );
 }}}
 which isn't terrible, but seems fragile if core changes in the future, and
 there should just be a better way :-)

 Two ideas from dev chat are triggering custom events or the (coming soon)
 "js actions" which would be more robust (like php actions).
