Warning: The type attribute is unnecessary for JavaScript resources

Hey. Again. Thank you for an amazing form builder…

The HTML validation throws a single warning for the following code:
<script type="text/javascript" id="wsf-wp-footer">

Screenshot: https://snipboard.io/w9Lv4Z.jpg

One possible workaround is to add a filter that removes the unnecessary type attribute:

/* Snippet seeks to remove the warnings when validating HTML on w3c.org: */
/*   Warning: The type attribute is unnecessary for JavaScript resources. */
	
add_action( 'template_redirect', function(){
	ob_start( function( $buffer ){
		$buffer = str_replace( array( ' type="text/javascript"', " type='text/javascript'" ), '', $buffer );        
		return $buffer;
	});
});

… that makes the site pass validation, but not including the type attribute in the first place, would be ideal.

Any recommendations?

Best regards
Bjarne
