`show-names` showing duplicate names #3245

This is on a private PR, so I can't share the link. It appears GitHub is already adding the real names of users to the comment header:

This occurs for other users in the thread, but my co-founder's name is long enough to take notice. I haven't seen this in public repos, only private ones in orgs.

Here's the HTML I'm getting:

html <strong> <a class="author link-gray-dark css-truncate-target rgh-fullname" show_full_name="true" data-hovercard-type="user" data-hovercard-url="/users/thephw/hovercard" data-octo-click="hovercard-link-click" data-octo-dimensions="link_type:self" href="/thephw">thephw</a> <span class="css-truncate expandable"> <span class="css-truncate-target text-normal ml-1" style="max-width:175px;">(Patrick Howard Wiseman)</span> </span> </strong>
