[walker-nav-menu] Undefined property stdclass::$current in class-walker-nav-menu.php

[winston_wolf]

In wp-includes/class-walker-nav-menu.php line 177 there's a missing empty(); function around $item->current.
Causes PHP errors everywhere wp_nav_menu(); function occurrence:

$atts['aria-current'] = $item->current ? 'page' : '';

Should be:

$atts['aria-current'] = ! empty( $item->current ) ? 'page' : '';

Hello @winston_wolf,
In the WordPress update version, we are facing the exact same issue,

In wp-includes/nav-menu-template.php line 190 there’s a missing empty();
function around $args->container_aria_label.
Causes PHP errors everywhere wp_nav_menu(); function occurrence:

$aria_label = ( 'nav' === $args->container && $args->container_aria_label ) ? ' aria-label="' . esc_attr( $args->container_aria_label ) . '"' : '';

Should be:

$aria_label = ( 'nav' === $args->container && !empty($args->container_aria_label) ) ? ' aria-label="' . esc_attr( $args->container_aria_label ) . '"' : '';

Thanks
