This is a follow-up for MBS-2966 (← BTW this ticket rules, thanks).
I think the use of this <span class="name-variation"> could be improved in two ways :

• Put the original name as title of this span instead of title of the a child
• Consistently do same everywhere. For instance, there is inconsistency here where the title of each recording shows its original name but the title of release artist shows the name variation instead (which is bogus anyway as it's already the a text content). Maybe I should look for other inconsistencies.
