We've just displayed an error message in it, so don't close it. I'm not sure if this code matters at all though. Usually when there's an error during loading, code in MobileFrontend will close the overlay and display an error message in a different way, so our message won't be visible to the user. But maybe there's some case I'm missing, and it's harmless. Closing the overlay was messing with the MobileFrontend code though. (found when working on I5146b726c5ce213992febb23f24c5937db0b9bfe) Change-Id: Id1ea44d7bf6ef0f4fc0285e9e606dd415ed0a947
