@SannaInc Thank you so much for reaching out. After reaching out to the company regarding this site we were able to give this page a test-drive and it no longer repros in Edge 78.0.277, below is a comparison of Edge Canary & Chrome Canary:
Chrome is left, Edge is right
If you can make sure your Edge version is up to date and then test it again and let me know if it still repros. Thank you.
