Angular: should this be an invalid email address?

I checked with online email validators and they claim it's incorrect format. But in angular and html5 "email" input field, it seems to be accepted:

[email protected]

Should our website allow a user with such an email address to create an account (where there is a trailing-period after the user handle)? Or is such an email handle invalid/impossible by RFC standards.

RFC 822 defines the local-part (section 6.1) as word *("." word), which means that after the dot there must be a word. word is defined (section 3.3) as atom / quoted-string and atom is 1*<any CHAR except specials, SPACE and CTLs>, quoted-string is a string inside quotes.

So this clearly says that after a dot there must be something and an address of form [email protected] is in fact invalid.
