The problem

Demo

1. On initial render, the view is

<div class="text-base font-bold">
  <a>hello</a>
  <button>toggle</button>
</div>

2. Click on the toggle button, the <a> element becomes

<a href="https://github.com" title="hello">hello</a>

3. Click on the toggle button again, the <a> element becomes

<a href="">hello</a>

What I really want is <a>hello</a>
