plugin/fragment: node order breaks after updating Alpine.js

[rameel]

Updating Alpine.js to 3.16.2 breaks node ordering when using x-fragment.
It reliably reproduces with 3 items, with other counts it looks fine on a quick check.

<!doctype html>
<html>
<body>
  <div x-data="{ items: [1, 2, 3] }">
    <button type="button" @click="items.reverse()">Reverse</button>
    <template x-for="n in items" :key="n">
      <template x-fragment>
        <span x-text="n"></span>:<span x-text="n"></span>
      </template>
    </template>
  </div>
