Adding Additional HTML Attributes to Link
Any initial HTML attributes on a <bolt-link>'s inner <a> tag will be retained with two exceptions: inline styles (auto-removed to avoid styling issues) and any HTML attributes that are in direct conflict with the props passed into the web component.

Links retain most HTML attributes 

<bolt-link>
  <a href="https://google.com" data-analytics="click">
    Links retain most HTML attributes
  </a>
</bolt-link>
 Most (But Not All) HTML Attributes Supported For example, the url prop passed along to this web component will override any initial HTML href attribute present.

Props > Initial HTML Attributes 

<bolt-link url="https://www.google.com">
  <a href="https://google.com" style="color: red">
    Props > Initial HTML Attributes
  </a>
</bolt-link>
