Type attribute is unnecessary for JavaScript resources

Hi

The Akismet plugin adds the javascript using following code to the website source code:

<script async=”async” type=’text/javascript’ src=’https://www.example.com/wp-content/plugins/akismet/_inc/form.js?ver=4.0.3′></script&gt;

If we run W3 validator, it shows following warning:

The type attribute is unnecessary for JavaScript resources.

So the correct code should be:

<script async src=’https://www.example.com/wp-content/plugins/akismet/_inc/form.js?ver=4.0.3′></script&gt;

Can this be corrected in next version?

Thank you.
