Named styles are broken when openpyxl opens and closes workbook
*Created originally on Bitbucket by [TomBrown10 (Thomas Brown)](https://bitbucket.org/%7B27f0cc06-2888-47fb-b322-10e1036098f2%7D/)*
The attached file has 4 custom named styles. With openpyxl I simply open the workbook and then save it as "out.xlsx". One of the named styles now has a different font color, and the "Normal" style has also changed!
