It's a bug, yes: such a setup was never implemented in the repo browser.
If the intermediate folders of your externals are versioned, then it works.
But your externals are inside unversioned folders, and unversioned
folders do not exist in the repo browser. So there's nowhere to 'attach'
the external folders in the repo browser tree.
