https:// link to google fonts causing mixed content warning

Hello,

I’m trying to clean up “mixed content” warnings on an https:// site (thanks, letsencrypt.org! ?? and am seeing this in your sources:

/htdocs/wp-content/plugins/google-maps-widget/css/gmw-admin.css:@import url(https://fonts.googleapis.com/css?family=RobotoDraft:regular,bold,italic,thin,light&lang=en);

…can you fix this to please be a https:// link? That should work fine on https:// sites… on https:// sites this leads to a “mixed content” warning in many browsers.

Thanks a lot
Nils
