page is not displayed in the breadcrumb list

[12rambau]

chevron is now correctly aligned. But the example page you linked to reveals another problem (also there in main) which is that the final element of the breadcrumb is completely missing on that page (and on all of the numbered "test of ..." pages in that section of the site). If you can tell why immediately maybe add that fix here too; otherwise we make a separate issue/PR I guess.
