When use auto imported apis, the sourcemap will be babel transpiled

[serialine]

Describe the bug

1. using Manual import

Original source

<script lang="ts">
import { ref } from "vue";
import { defineComponent } from "@nuxtjs/composition-api";

export default defineComponent({
  setup() {
    const a = ref();
    async function b() {
      return await Promise.resolve();
    }
    return { a, b };
  },
});
</script>

Generated source (chrome devtool sourcemap)

import { ref } from "vue";
import { defineComponent } from "@nuxtjs/composition-api";

export default defineComponent({
  setup() {
    const a = ref();
    async function b() {
      return await Promise.resolve();
    }
    return { a, b };
  },
});

2. using Auto import

Original source

<script lang="ts">
// import { ref } from "vue";
// import { defineComponent } from "@nuxtjs/composition-api";
export default defineComponent({
  setup() {
    const a = ref();
    async function b() {
      return await Promise.resolve();
    }
    return { a, b };
  },
});
</script>

Generated source (chrome devtool sourcemap)

import _asyncToGenerator from "@babel/runtime/helpers/esm/asyncToGenerator";
import "regenerator-runtime/runtime.js";
import "core-js/modules/es.object.to-string.js";
// import { ref } from 'vue';
// import { defineComponent } from '@nuxtjs/composition-api';
export default defineComponent({
  setup: function setup() {
    var a = ref();
    function b() {
      return _b.apply(this, arguments);
    }
    function _b() {
      _b = _asyncToGenerator( /*#__PURE__*/regeneratorRuntime.mark(function _callee() {
        return regeneratorRuntime.wrap(function _callee$(_context) {
          while (1) switch (_context.prev = _context.next) {
            case 0:
              _context.next = 2;
              return Promise.resolve();
            case 2:
              return _context.abrupt("return", _context.sent);
            case 3:
            case "end":
              return _context.stop();
          }
        }, _callee);
      }));
      return _b.apply(this, arguments);
    }
    return {
      a: a,
      b: b
    };
  }
});
