Comment (by caercam):

 Spent some time playing with this issue today, still happens with
 WordPress 4.8.1. First it seemed to be a known --and solved-- bug from
 MediaElement.js (See
 [https://github.com/mediaelement/mediaelement/issues/1819 ticket] and
 [https://github.com/mediaelement/mediaelement/pull/1826 PR]) so I tried
 overriding the shipped MediaElement version (2.22.0) with the fixed
 version (2.23.0), but after some fiddling I realized all that's needed for
 the duration to be displayed properly is the correct time format. Adding
 this snippet to my site did the job:

 {{{#!php
 <?php
 add_filter( 'mejs_settings', 'change_mejs_time_format' ) );
 function change_mejs_time_format( $mejs_settings ) {

         $mejs_settings['timeFormat'] = 'hh:mm:ss';

         return $mejs_settings;
 }
 }}}


 It's worth noting that changing the time format applies to ''all'' media,
 so you could end up with 10 second videos with a total time display
 "00:00:10". @Dexterity if you're OK with that side-effect you can fix your
 example site.
