BreadcrumbList structured data 2018 update

The navigation breadcrumb metadata format that Google relies on was updated in August 2018. It now requires a new position field for each item that looks like this:

<meta itemprop="position" content="1" />

This is an integer for the item depth/distance from the top level. If you are using the custom component to override the breadcrumb please update with the new code to include this itemprop from the best practice article here:
