The breadcrumb are not aligned between cristal and xwiki

Analysis

This is a combination of two things:

1. the first "Home" segment that should be an icon (or not be there at all)
2. the segments that are using the id of the page instead of it's title

For the second point, the rest endpoint (e.g., http://localhost:8080/xwiki/rest/wikis/xwiki/spaces/A/spaces/B/pages/WebHome for A.B.WebHome) does not return the actual titles, so we need to either find another access point, or improve the rest endpoint to have the relevant information returned.
