  // Awful hack: Flexbox column wrapping doesn't work properly in most major
  // browsers -- the element boundary does not expand to cover the full wrapped
  // content as it should. This results in the wrapped 'content' appearing
  // outside the element background (the linear gradient in this case). The
  // workaround is to use flex row direction for both rows & columns, and use
  // vertical-lr/vertical-rl as the writing mode for columns -- resetting
  // writing-mode for descendant elements.
