Comment (by isoftware):

 Thank you for your swift repsonse.

 I have the following shortcode on a site that has only one admin user so
 all content is created from admin:


 {{{
 ...
 <a data-slide-index="[counter-increment output='true']" href="#"></a>
 ...
 }}}


 On debug I can see that the counter-increment shortcode is returning the
 correct integer value but after the wp_kses_attr_check returns false,
 wp_kses_one_attr returns empty string and the returned shortcode content
 is :


 {{{
 ...
 <a href="#"></a>
 ...
 }}}
