Navbar-nav list type not being respected on refresh in Edge

Created by: jonny64bit

So if you load up this bootstrap 4 example in Edge with the browser window in md or above

Shrink the window so you see the navbar-toggeler and expand.

Refresh the window and expand again.

You'll see the that list-style: none; isn't being respected.

i've checked this in chrome, firefox and IE11 so this looks to be a edge only bug.
