No. I did not.
There really is no good visual cue to prompt the user to do so.
However, once I did, I do also find the entry, as you describe.
I would still describe this as a UI flaw based on two things.
The lack of visual cue, and the need to take multiple actions to achieve a single result.
The old fashioned folder icon which 'opens' the page to the contents of a parent may be old fashioned, but it definitely is well known and effective. In fact, I've got a couple of customers who are pretty upset about the possibility of losing this UI affect if they migrate their carts.
