There are two errors in web console (web developer tools in browser) regarding breadcrump markup of the Domain Explorer page.

Appears when user navigates from /DomainExplorer to a specific Domain using a link - see video in attachment.

1. Warning: Each child in a list should have a unique "key" prop.
   
   Check the render method of `DomainExplorerDashboard`. See https://fb.me/react-warning-keys for more information.
