How is this dealt with now?

No need to deal with this now, I think. This was added when Instant used to
support URLs. The default search engine is not expected to cause an auth dialog.
If it does, the load will never complete, so the engine will never be deemed to
support Instant.

I have put a TODO on my list to add a browsertest for this.

-  // (the load remains pending) until the user cancels or succeeds in
-  // authorizing. Since we don't allow merging of WebContents with pending loads
-  // we disallow auth dialogs from showing during instant. Returning NULL does
-  // that.
-  // TODO: see if we can handle this case more robustly.
-  if (request->extra_request_headers().GetHeader(
-          InstantLoader::kInstantHeader, &instant_header_value) &&
-      instant_header_value == InstantLoader::kInstantHeaderValue)
-    return NULL;
   return CreateLoginPrompt(auth_info, request);
