Screenshot showing the XHR failure

Filing on behalf of Jeffrey Posnick:

 Technology Preview 49
 Uses a custom bundle of Workbox [1]

Issues observed:
 - At one point, I received a "This page was automatically reloaded due to an error" (or message along those lines). I couldn't capture any logs or screenshot.
 - When visiting a search page [2] and reloading a few times, I was able to get into a situation in which an XHR request failed due "access control checks". The strange thing is that a) I don't belive the SW intercepts that traffic and b) it's a same-origin request. [ATTACHMENT]
 - The offline-game functionality works as expected.

The failed XHR is strange, though, and I was able to trigger a mysterious forced-reload.
