Named styles are broken when openpyxl opens and closes workbook
Created originally on Bitbucket by TomBrown10 (Thomas Brown)
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!
