How to reproduce:
1. Go to any profile. Click any of "add parent/spouse/child"
2. Input "First Name at Birth" = Jacques Bonaventure
3. Input "Last Name at Birth" = L'Italien
4. Enter "Birth Date" = 1718-11-17
The system will suggest a profile (L'Italien-3) but the link [set as father] will not work.
The HTML generated:
<span class="pseudolink" onclick="setAsWho("L" italien-3");'="">set as father]</span>
