If the plugin submits to itself, with the GET variable noheader, and then manually includes `wp-admin/admin-header.php`, the hook doesn't appear to run. I can't seem to find any official documentation on `noheader`, but the method I am using is described all over the internet. I will try attach a short plugin that demonstrates the issue.
