Breadcrumb key-value pair not displayed if value is null

Is there a reason why the key-value pair of a breadcrumb is not being displayed when the value is null? I personally prefer to still see them even if they don’t have the values as seeing the keys also helps.

And is there a way for me to change this? I would really want to display every single key-value pair regardless of the value.

Ping @untitaker ?
