CSS selectors for fonts not generated correctly when a font changes based on a media query

Original CSS-

@media(min-width:720px) {
  .class {
    font-family: "EB Garamond", serif;
  }
}

This would render as-

@media(min-width:720px) {
  .class {
    font-family: "EB Garamond", serif;
  }
  .eb-garamond @media(min-width:720px) {
    font-family: "EB Garamond", serif;
  }
}

This isn't correct CSS, so fonts being set inside a media query weren't being set correctly when they loaded. Correct CSS would be-

@media(min-width:720px) {
  .class {
    font-family: "EB Garamond", serif;
  }
  .eb-garamond .class{
    font-family: "EB Garamond", serif;
  }
}

Patch filters out selectors that start with "@media" and looks for the selector inside.
