What wrong?
- The bad design of the caption for the collapsed table - The text with more chars/words is render as "narrow column". See collapsed tables on the page https://meta.wikimedia.org/wiki/Movement_Charter/Drafting_Committee/Elections/Feedback#The_largest_according_of_the_local_wiki_for_voting_users
How is right?
- If the table is collapsed, then the table caption rendering as HTML element as block (as CSS).
