Display name isn't shown as alt text anymore

Moving the mouse cursor over the profile picture in the upper right corner doesn't show a user's display name anymore, but "User profile" instead.

Did someone change "<img src="${avatarUrl}" alt="${nameWithHtml}"/>" to "<img src="${avatarUrl}" alt="$i18n.getText('user.profile')"/>" in \atlassian-jira-6.3.14-source\jira-project\jira-components\jira-plugins\jira-header-plugin\src\main\resources\templates\user-profile.vm by accident?
