Switching to any other branch gives a 404 error from the server. This only happens (as far as I can tell) if you are using the Edge browser. I tested with Edge 18 on a VM. ### Example Project I tested on this repo, gitlab-org/gitlab-ce, and one that we self-manage in our organization. I suspect it is not specific to the project, though. ### What is the current *bug* behavior? User gets a 404 page. Kinda looks like it is trying to do a redirect, and maybe the URL got encoded wrong. ### What is the expected *correct* behavior? Selected branch should be shown. ### Output of checks This bug happens on GitLab.com
