Description

Using the classic editor, it's possible to exclude post types and taxonomies from appearing in the link builder using:

function my_custom_link_query( $query ){
$query['post_type'] = array( 'post', 'pages', 'snippets' );
return $query;
}
add_filter( 'wp_link_query_args', 'my_custom_link_query' );

Gutenberg does not appear to support this same level of filtering of link builder arguments. All post types and taxonomies are available as link options by default.

Expected behaviour

Feature parity with classic editor enabling the filtering of link builder arguments.

Actual behaviour

All post types and taxonomies are available, even when filters are applied via wp_link_query_args
