Excessive backslash stripping when editing in Gutenberg about cloudinary_wordpress

[mattleff]

My current workaround:

array_map(
    function ( $type ) {
        add_filter( 'rest_prepare_' . $type, function( $response, $post, $request ) {
            $context = $request->get_param( 'context' );
            if ( 'edit' === $context ) {
                $data = $response->get_data();
                $data['content']['raw'] = addslashes( $data['content']['raw'] );
                $response->set_data( $data );
            }
            return $response;
        }, 9, 3 );
    },
    get_post_types_by_support( 'editor' )
);
