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;
}

研究方向
Start by reproducing the issue using the provided CodeSandbox. Investigate the rule insertion order in JSS by examining the StyleSheet or Rule classes, particularly looking for any sorting logic. Focus on how JSS handles selector specificity when generating CSS rules. Check existing comments in the issue for any hints or partial solutions.
