I don't remember if previous version did this or not, so bear with me.
On an ad page, between the search bloack and the ad content is a navigation tree that looks like:
Home >> [Sub-Category] >> [Ad Title]
In 18.104.22.168 I have noticed that the entire navigation tree is not visible. Shouldn't it show:
Home >> [Category] >> [Sub-Category] >> [Ad Title]
