This is not a bug, it's how web apps are supposed to work. The url should be updated to reference the current app view - this way you can copy the url for that particular resource and access it again by pasting with the same url. This is how it worked for headers when websites were just plain documents. It's a very powerful feature and is exactly what the web is about - sharing resources easily. Browsers have different ways of dealing with this like grouping items in the back history by domain, so that it's easy to leave the site back to page previous to the app session.
