1. Create a new Calc document 2. In A1, type something, e.g. "abc" 3. Check the cell's font (Liberation Sans by default), and the default cell style (also shows Liberation Sans) 4. In Excel, create a new document 5. In Excel, type something to A1 (e.g., "xyz") 6. Check the cell's font (Calibri by default) 7. Copy A1 from Excel to clipboard 8. In Calc, select B1, and paste => At this point, A1 changes font to Calibri; and that is caused by Default style changing font to Calibri. Possibly related to Writer's bug 151728.
