Daylen, thanks for this note. I've filed phab:T170466. It might be helpful if you could tell me what version of Edge you're running, and what your OS is.
@Whatamidoing (WMF) Microsoft Edge 40.15063.0.0 on Windows 10 Pro Insider Edition (build 15063). I have already added it to the Phabricator task. Thanks!
