This test was accidentally taking advantage of the fact that closing a tab will result in a nested event loop while waiting for the permitUnload messages to be sent back and forth from the content process. This meant that the message that tells the parent that the browser (which is having its history set) can now go back had a chance to be received by the parent. With the patches in bug 1336763, we're no longer spinning the event loop if the closing tab doesn't have a beforeunload event handler in it, so we need to wait for the browser to report that it can go back before actually sending it back in order to avoid a test failure.
