Thanks for working on this change, @robrez. Can we get this change verified against Edge too?

[robrez]

Please advise...

I don't have access to a windows10 machine and I'm not sure how/if I can setup wct to test against edge when edge isn't locally installed.

The best I've been able to do is run IE11 w/ emulation set to edge. Everything ...looks... okay in emulation mode.

I did try using Remote Test IE but the remote desktop session isn't working - maybe related to my workplace firewall. I'll try this again later from home.

[addyosmani]

No worries. We'll get it tested on Edge and report back.

I've tried it out on the latest versions of {Windows, OS X} × {Edge, IE, Chrome, Firefox, Safari} and it looks good.
