[Vue3][JSX] Vue Fails to Track Dynamically Computed Class Names in JSX, Causing CSS Processor to Ignore Styles (Two Instances)

Describe the bug

I am making a configuration file editor. But I encountered two problems,

1. The class generated by jsx is not captured by vue, which causes the style of <style scope> to be considered never used. As a result, the rendered page uses the class name rc1 but no corresponding css is generated. I can only remove the scope to make the style effective globally.
2. Tailwind believes that the class generated by jsx calculation does not exist, so it does not correctly generate the corresponding style. I can only stop using tailwind and switch to inline style

  <ConfigFrom/>

<script setup lang="jsx">
import {ref, computed, watch, reactive} from 'vue'

const props = defineProps({
  configData: {
    type: Object,
    required: true
  },
  configDesc: {
    type: Object,
    required: true
  }
})

const configDescMap = reactive(new Map(Object.entries(props.configDesc)))

const rainbowColor = [
  "rc1",
  "rc2",
  "rc3",

  const colorLevel = level % 7;
