Wrapped array value dont work correctly

[KoreSamuel]

codesandbox here

versions: "vue-function-api": "^2.1.1"

<script lang="ts">
import { createComponent, value, Wrapper } from "vue-function-api";

export default createComponent({
  setup(props, context) {

    const tabs: Wrapper<string[]> = value(["tab2"]);
    tabs.value.push("tab3"); // ['tab2', 'tab3']

    // should ['tab1', 'tab2', 'tab3'] but ['tab2', 'tab2', 'tab3']
    tabs.value.unshift("tab1");

    // worked correctly
    const tabs2: string[] = ["tab2"];

    tabs2.push("tab3");

    // ['tab1', 'tab2', 'tab3']
    tabs2.unshift("tab1");

    return {
      tabs,
      tabs2
    };
  }
});
</script>

by the way, version 2.0.6 worked fine
