What is the difference between "Copy email address" and "Copy" in Google Chrome?

Question

JavaScript

I am sending goals to GTM by event, there is such a handler:

$('a[href^="mailto:"]').bind('copy', function(e){
     dataLayer.push({ 'event': 'email-copy'});
   });

If you select the text and press Ctrl + C - it is sent,
If you select the text and right-click, select "Copy" in the menu - it is sent,
But if you right-click and select "Copy email address" in the menu, it is not sent.
Has anyone caught such an event?
