Chrome Dev console shows that the italics font is indeed named "dm" just like the rest of the content. It is not really a cursive, only a few letters are stylized ("f", "s" and "l").
It is possible (and often desirable) to use different WOFF fonts for italics, and they can look quite different from the standard font.
