YOAST does not allow skype or whatsapp in menu items

Hi, I added skype and whatsapp protocols:

function add_more_protocols ( $protocols ){
	$protocols[] = 'skype';
	$protocols[] = 'whatsapp';
	return $protocols;
}
add_filter( 'kses_allowed_protocols' , 'add_more_protocols' );

Then, I was able to add these links as menu items (custom links): skype:username?call, whatsapp://send?text=Visit....
And they worked.

But, when I enable Yoast, the skype and whatsapp urls are cleaned and replaced by home url.
I think Yoast should respect the enabled protocols.
Can you solve it?
Thanks
