 /**
  * Set the "wrap text" option if a cell of the given row contains a new line.
  *
  * @NOTE: There is a bug on the Mac version of Excel (2011 and below) where new lines
  *        are ignored even when the "wrap text" option is set. This only occurs with
  *        inline strings (shared strings do work fine).
  *        A workaround would be to encode "\n" as "_x000D_" but it does not work
  *        on the Windows version of Excel...
  *
  * @param \Box\Spout\Writer\Style\Style $style The original style
  * @param array $dataRow The row the style will be applied to
  * @return \Box\Spout\Writer\Style\Style The eventually updated style
