font-style italic not working

Hi, great plugin especially when you have a lot of websites where you need local fonts!

I tested this plugin on multiple websites and it breaks italic font-styles, i.e. italic fonts are displayed non-italic.

When I had a look at the generated CSS, you can see that italic fonts use the same woff/woff2 files as their non-italic counterpart.

Can you please advise?
