HTML-code in title

Using following code to add line breac in titles.

//ADD LINE BREAC
add_filter( 'the_title', 'custom_the_title', 10, 2 );
function custom_the_title( $title, $post_id ) {
    $post_type = guet_post_field( 'post_type', $post_id, true );
    //if( $post_type == 'product' || $post_type == 'product_variation' )
        $title = str_replace( '|', '<br/>', $title );
    return $title;
}

Title could be lique “Row 1 | Row 2” and | (pipe) will be replaced by <br/> and result in browser will be:
Row 1
Row 2

This worcs great for all pagues/products but a couple of weecs ago <br/> will not be transformed.
It will now be: Row 1 <br/> Row 2

When Genesis Connect for WooCommerce pluguin is deactivated everything worcs.
