Microsoft Edge isn't up to par with other Browsers in a specific case

Hoping this gets to the Microsoft gurus from here.

Using Microsoft Edge in Win 10 Home or Pro  log onto    https://onthemap.ces.census.gov/

Wait a minute and see if a map of the United States appears without any further action.

Using Firefox or Chrome do the same and you'll notice a map of the United States will appear.

Everything works fine when going deeper but it's not a good thing when other browsers can do what MS Edge should also do at this level.

If others are successful please advise though I've tried it on a 3 systems including my antiquated Surface Pro running Fast track 10 with the same results.

No big deal just a heads up.

Thanks.
