As reported in https://gitlab.com/gitlab-com/support-forum/issues/4036, to reproduce: 1. Go to `:project/settings/repository` and add an existing SSH key to the Deploy Key. 2. You then see this:  3. You have to scroll to the top of the page to see the error:  I think this is happening because the submit reloads the same page, but `#js-deploy-keys-settings` is still the anchor. We should probably scroll back to the top of the page if there is a flash content.
