### Summary If I visit a page in GitLab and then navigate away very quickly afterwards, before all the JavaScript has finished executing, I can consistently cause error banners to show up ### Steps to reproduce * Visit, e.g., https://gitlab.com/gitlab-org/gitlab-ce * Click a link elsewhere, or enter another URL in the address bar, really quickly. ### What is the current *bug* behavior? Red banners appear on the screen until the new page replaces the existing content(What actually happens) ### What is the expected *correct* behavior? This sort of request failure doesn't need to be communicated to the user. It's distracting and looks really bad. ### Relevant logs and/or screenshots  ### Possible fixes Hopefully the browser tells us *why* the request has been prevented from completing. We can use that information to skip displaying the banner
