 Using latest WordPress development version 6.3-alpha-55505-src, when
 submitting a form with field values that are array, and the array key is
 one of WordPress query vars, that causing sanitize error for 'post_name'
 parameter in get_posts function.

 {{{
 <form method="post" action="">
 <input type="text" name="custom_post_type['post_title']" value="This is a
 test post">
 <input type="submit" value="Send">
 </form>
 }}}
