描述

Take the following style as an input:

const style = {
  root: {
    "&:hover": {
      "& .icon": {
        color: "red"
      }
    },
    "&.active": {
      "& .icon": {
        color: "blue"
      }
    }
  },
};

Expected behavior: I would expect the following CSS injected into the page:

.root-0-0-1:hover .icon {
  color: red;
}
.root-0-0-1.active .icon {
  color: blue;
}

Describe the bug: The following CSS is injected in the page:

.root-0-0-1.active .icon {
  color: blue;
}
.root-0-0-1:hover .icon {
  color: red;
}
