Attached image URL spoofing.png

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.163 Safari/537.36

Steps to reproduce:

http://www.xn--google-e4d.com/

By adding this * ̣ * (notice the DOT under asterisk) we can actually spoof the URL (espicially the inexperienced users)

Actual results:

http://www.goog̣le.com/

Expected results:

The URL should be shown in PunnyCode

This is a variation of the problem in bug 1405845. To the extent registrars are letting these through (are they really?) the best solution is represented by bug 1507582 (see the example URL in that bug: airfrance with a dot under one of the characters).
