There's not really a good reason for Google to make applications they create work outside their own run-time environment - Chrome. Any technical reason they might offer (sparse array performance) is just facetious. They have the technical know-how to solve such problems, but business wise it makes little sense.
I use three web browsers for just that reason. Chrome for Google products (YouTube, Gmail, now Inbox, etc.), IE for Microsoft products (Outlook.com, etc.), and Firefox for the open web and general usage.
