Steps to reproduce:
- Create a subwiki for global users (so that we have both home and the subwiki in the breadcrumbs)
- Go to the subwiki
- Expand the breadcrumb tree for the home element
- Observe that it displays the path to the current document, in the current wiki only, instead of displaying the full path, starting from the main wiki (including the subwikis and ending with the current document).
