Scenario: You have a page at /columbia. You create a node URL alias for it: /how/to/get/how/to/get/to/columbia/street

So, /how/to/get/how/to/get/to/columbia/street redirects to /columbia – that's good.

But if you access /how/to/get/how/to/get or any partial path, it just loads the homepage. The expected behavior is to load a 404 page.
