Changing Branches fails using Edge 18
Summary
Switching branches on the repository view fails in Edge.
Steps to reproduce
When on the main repository view, or when viewing the contents of a file, there is a drop-down box to switch branches. 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
