When I clicked on the padlock icon of the example site https://www.xn--e1awd7f.com/ in Android Chrome, the immediate dialog box showed the real site URL. When I clicked on Details, it showed the certificate as issued to epic.com instead. Wild stuff.
Using Cyberfox on windows 10, clicking on the padlock --> more information --> view certificate showed the certificate was issued to www.xn--e1awd7f.com
