Too long email address on profile page
Summary
Since !1387 (merged) the internal email address is shown in the info box of the profile page. For long surnames the address doesn't fit into the box, especially on smaller displays because the box width depends on the browser window's size.
Steps to reproduce
a) Go to your profile page and make the window narrower b) In the local environment: change the name of a user with a mailbox to a long surname (e.g. in the database), login as that user and check the profile page
What is the expected correct behavior?
Adding a line break before or after the "@" might be an option. Maybe there is a neat css solution?
