• Wrapping of long menu with many crumbs seems broken:
  
• if there is the space, it is not used (example: very long repo names)
  
• on mobile, the text is just cut without an ellipsis
  

Possible solutions:

• the crumbs don't need to be floated left, inline rendering should be enough (with some mods of course)
• the max-width could be calculated with a css var that holds the number of items. Just a hot take:

max-with: max(240px, calc(80vw / var(--item-count)))
