4.7.6 has this problem
Same problem. I was using 4.6.8. It worked fine. Today, when I deployed a new server with npm install. It installs 4.7.6 with firstname.lastname@example.org which has the regression.

Guessing this is a duplicate of #4867 but can you please post a code snippet or follow the issue template please so we can at least see what's causing the bug?
