Unable to see user info (email) on a file or project

Within the past year, the feature to view a user’s email while hovering on their avatar has been removed.

This happens on files that I own and have been invited to view/edit. Previously, if you scrolled over the person’s avatar in the “Shared” popup of a file, their email address would be reveal in a tooltip. I’m wondering if there is a way to get further information of users in a file, since some users have just their first name or initials. It would be nice to be able to send out a message/update to all users that are added to a particular file, or find their emails so they can be sent communications.
