Sandstorm provides an API to the app through which it can update the URL in the address bar -- adding an arbitrary path after the grainId, which will then be passed back to the app if the URL is re-opened. Lychee and MediaWiki use this, for example. It sounds like Gitlab should too -- that would be a good bug to file.
