Comment:
@DrewAPicture Actually, the Customize Posts plugin actually doesn't use
the preview nonce since the data is part of the customizer changeset, and
so the UUID is used instead.
@Webbverkstaden You'll want to look at the [https://github.com/WordPress
/wordpress-develop/blob/4.8.0/src/wp-includes/revision.php#L508-L554
_set_preview() and _show_post_preview()] functions.
But before that, you'll want to look at [https://github.com/WordPress
/wordpress-develop/blob/4.8.0/src/wp-includes/class-wp-query.php#L2938
this line] in `WP_Query`:
{{{#!php
<?php
if ( $this->is_preview && $this->posts && current_user_can( $edit_cap,
$this->posts[0]->ID ) ) {
}}}
It could be an issue with mapping the meta caps to the primitive caps in
your CPT. It's looking at the `edit_post` meta cap (here stored in the
`$edit_cap` variable).
