- open excel first line changes font , size, on every file in different calibri time new roman. font size stays correctly increased.

- if click on cell (often!) correct font shows in toolbar if click inside , mark line see incorrectly in toolbar. 

- if cell contains multiline content first line correct formated lines afterwards not.
