     The parent containers (.results, #leaderboardBody) already had
     overflow-x:auto — but the tables themselves were still forced to
     width:100% with wrapping cell text, so they always shrank/wrapped
     to fit instead of actually growing wider than the screen. There was
     nothing to scroll TO. Letting the table size to its own content
     (min-width:100% as a floor, not a ceiling) and stopping cells from
     wrapping is what makes columns overflow for real — which is what
     the scroll container needs in order to do anything. */
