ordered list number label font-size

[CodePlayer7]

now it seems that the number label of ordered list has a fixed fontSize and fontFamily, would it be performance that the number label style follows the first letter of the line?

and after changing the font family,the font size of next inputing text will be of the line, would it be better that the new input text font size keep same with the former.
