Function to detect if current page is a preview of a draft

[paulschreiber]

It would be very helpful if there was a function to detect if the page being viewed is a preview of a draft. Call this is_draft_preview().
Currently, you can achieve this check with code like this:

<?php
function is_draft_preview() {
    global $post;
    $is_draft = 'draft' === $post->post_status;
    return ( is_preview() && $is_draft );
}

This seems to be pretty much the same as #42088 and the same answer but using draft for the $post_status.

Same conclusion, time to close it as maybelater, but again I doubt this should ever be added.
