20438	Custom Post Types with Post Format support aren't registered against post_format taxonomy	batmoo		"When a custom post type adds support for {{{post-formats}}}, this doesn't actually register the {{{post_format}}} taxonomy for the post_type.

Here's a quick test:

{{{
add_action( 'init', function() {
        register_post_type( 'not-post', array( 'supports' => 'post-formats' ) );
        global $wp_taxonomies;
        var_dump( 'post supports post_format:', in_array( 'post', $wp_taxonomies[ 'post_format' ]->object_type ) );
        var_dump( 'not-post supports post_format:', in_array( 'not-post', $wp_taxonomies[ 'post_format' ]->object_type ) );
} );
}}}

The {{{post_format}}} taxonomy doesn't get returned when {{{get_object_taxonomies}}} is called for the custom post type and one side-effect of this is that the {{{post_format_relationships}}} cache does not get flushed by {{{clean_object_term_cache}}} leading to stale values when a post format is changed.

(The {{{post}}} post_type is immune to this because core registers the {{{post_format}}} taxonomy with it.)

When a post_type adds support for post-formats, an explicit association should be made between the post_type and the {{{post_format}}} taxonomy."	defect (bug)	new	normal	Awaiting Review	General		normal		close	batmoo wordpress@… sararcannon@…
