Filter on the "Manage members" page not working

Problem/Motivation

We have custom filters on the "Manage members" group page and they are not forking because of the added custom submit to the exposed filter form

Proposed resolution

Replace
$form['actions']['submit']['#submit'][] = '_views_manage_members_exposed_form_submit';
with
$form['#submit'][] = '_views_manage_members_exposed_form_submit';
