title: phpexcel - comments misplaced in xlsx 2010 workbook
body: <p>When I modify a comment in an excel workbook (2010, 2013) created by PHPEXCEL, the <strong>comment is presented at the very top of the sheet</strong>. The same appears with the phpexcel example's script 05featuredemo.inc. 
  I'd like the comment to stay closed to the related cell. To do this, before modifying the comment, I must first change the alignment of the cell. Doing this it works. Another solution is to copy the sheet to a new workbook.</p>
