I don’t think this is an issue because abc.def@mail matches the pattern of a valid email address. As another example, root@localhost is a perfectly valid email address.

For more info, see Why does HTML5 form-validation allow emails without a dot?, where one of the answers mentions:

Because bar is a valid hostname, which makes foo@bar a valid email address.
Chrome is not going to check for you whether the address or host are actually in use, only whether the semantics are correct.
See http://en.wikipedia.org/wiki/Email_address#Domain_part for examples of valid email addresses.

Or How does HTML5 input type email works without top level domain name, where one of the answers mentions:

Because a@b is a valid email address (eg localhost is a valid domain). See http://en.wikipedia.org/wiki/Email_address#Examples
