WebDriver's implementation of deleteAllCookies discards its completion handler and returns success before the network process has actually deleted and saved the cookies. Since the delete process is asynchronous, we create a race condition that can lead to downstream test failures, implying bugs in WebKit that are not present in real Safari. Fixing this will avoid bugs in one cookie-based WPT from poisoning other steps.
