Improper redirect after adding a new user on Edge

Steps to reproduce:

1. Login with an Admin
2. Go to Administration: Users
3. Click "Add new user"
4. Fill in the required fields
5. Click Save

You get redirected to http://localhost:9090/xwiki/bin/view/XWiki/XWikiPreferences?xpage=registerinline and you see the Registration form without any styles.
If you go back to the previous page, you can notice the new user was properly created.

Tested on Edge v38.14393.0.0.
The bug doesn't reproduce on IE11, Chrome 57 and Firefox 52.
