Contact Form Editor: email address with 2 hyphens is seen as invalid

[arcangelinis]

Steps to reproduce

1. Starting at URL: https://wordpress.com/page/brilliant--basics.com/2
2. Edit the Contact Form from the Visual tab and then click Settings
3. Under "Enter your email address" use orders@brilliant--basics.com
4. You will receive an error stating "orders@brilliant--basics.com is not a valid email address." and will not be allowed to save

What I expected

This is a valid email address and a valid website, but the double hyphen is being flagged as not valid.

Work around

By using the Contact Form shortcode I was able to set the email address without any issues

Tested and confirmed that I am unable to change a contact form settings email address to an address using a domain with two hyphens in a row such as domainwith--twohyphens.com.

Hi, i also can reproduce this issue.

And i think this from third party library. I just create a PR on third party library to fix this issue https://github.com/manishsaraan/email-validator/pull/33

But any other options, to make it fix asap instead wait my PR to be merge? Thanks.

My PR already merged https://github.com/manishsaraan/email-validator/pull/33 Hopefully can fix this issue.
