 According to the jQuery documentation (https://api.jquery.com/hasclass/),
 the .hasClass() method accepts a class name without a prefixed . dot.
 An improper use of the method's argument, that includes the dot, has been
 found in the following files:

 /wp-includes/js/mediaelement/wp-mediaelement.js
 Line #47
 {{{
 return ! $( this ).parent().hasClass( '.mejs-mediaelement' );
 }}}

 Should be:

 {{{
 return ! $( this ).parent().hasClass( 'mejs-mediaelement' );
 }}}

 /wp-includes/js/mediaelement/wp-mediaelement.min.js

 Line #1

 {{{
 return!b(this).parent().hasClass(".mejs-mediaelement")
 }}}

 Should be:

 {{{
 return!b(this).parent().hasClass("mejs-mediaelement")
 }}}
