Data sent to core.submit_post_end event does not include fresh post_visibility

in includes/functions_posting, the $data array sent to the core.submit_post_end event does not contain up to date post_visibility as another variable is used ($post_visibility) to determine and process its value in submit_post() function.

$data['post_visibility'] should thus be set to $post_visibility before the core.submit_post_end event is triggered.
