spreadsheet containing problematic formula
When editing formula in cell, there is colorized text of used cells. Also refered cells are bordered by the same color.
If there is name of sheet that consists space (and possibly other special characters), apostroph in reference on such cell is used.
In this case textcolor and bordering of that cells is not working.
