Changing Branches fails using Edge 18
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.
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.
