Show the user's picture in Quiz doesn't show the name of the student

Here are the steps in order to reproduce:

1. As a teacher, create a test
2. Set the "Show the user's picture" to Yes.
3. As a student, do the test.
Result: The picture appears but not the name.

The description of this function specifies that the NAME and the PICTURE are to be shown. This is clearly not the case. Otherwise, a mouse-over on the picture will show the name of the student.

This was tested on 2.3.2.
