fix: failed to match the root v-scope node

[xunmi1]

createApp().mount('#app')

<div v-scope="{}">
  <div id="app">
    <div v-scope="{}" id="target">
       ...
    </div>
  </div>
</div>

Will not match the #target[v-scope] node.

This is intended... the nested v-scope will be processed during the walk so only root v-scope needs to be matched.
