We want an ordered list item's number to be rendered with default char
format, like the others in the same list, even if the list item's text
begins with a span that has a different char format. So insert the
list item's block with a default char format first, then change the
char format of the cursor to suit the text that's about to be inserted.
In HTML interpretation, it means the <li> does not have a style, but
contains a styled span.
