   7      This test has a number of tables, each with 2 flexboxes side-by-side,
   8      whose "width" values depend on the flexbox's min and/or pref widths.
   9
  10      There's not enough space for both flexboxes to fit side-by-side, so their
  11      width preferences must be balanced. This exercises
  12      nsFlexContainerFrame::GetPrefWidth() & ::GetMinWidth().
  13
  14      IN EACH CASE, div.a has these intrinsic widths:
  15        Pref width: 2*40 + 1*50 + 2*10 = 150px   (2*aaaa + 1*aaaaa + 2*space)
  16        Min width: 50px  (width of "aaaaa")
  17      and div.b has these intrinsic widths:
  18        Pref width: 5*20 + 3*10 + 7*10 = 200px   (5*bb + 3*b + 7*space)
  19        Min width: 20px  (width "bb")
