This code is still actual to remove ‘Quick Edit’ link under a post line at the posts list. I re-tested it with theme 2017 functions.php, I just used the ‘editor’ role instead yours:
if (current_user_can('editor')) {
add_filter('post_row_actions','remove_quick_edit',10,1);
}
function remove_quick_edit( $actions ) {
unset($actions['inline hide-if-no-js']);
return $actions;
}
Check if you inserted code to the active theme’s functions.php, if your test user really has ‘page-editor’ role.
I’m ready to look at your site on-line if you send URL and admin login credentials to support [at-sign] role-editor.com
