Inconsistent results with `gsutil ls`

I cannot explain why, but when I run `gsutil ls` I get different results for supposedly similar folders

In this image, the first folder returns just the children and the second command returns the parent as well. The folders are supposedly the same, so why is this happening?

Start by reproducing the two `gsutil ls` commands shown in the issue image and compare their results for supposedly similar folders. Read the `gsutil ls` entry point and related cloud-storage listing behavior; done means explaining the differing output and adding a regression test if the behavior is confirmed as a bug.
