[FIX] web: CP: long and clipped breadcrumb

=== ISSUE 1 ===

When the Control Panel breadcrumb was not displayed (eg. after reloading
the page), the name of the last element was used. In this case, the name
was not truncated and could create a layout issue if it was too long.

=== ISSUE 2 ===

The breadcrumb was clipped on Firefox, letters such as "p", "j" or "y"
where partially hidden. This was due to the combination of a too small
line-height and the `overflow: hidden` applied on `breadcrumb-item > a`.

This commit fixes these issues.
