Auto fill 'related to' field in compose mail popup when clicking on contact from within a case or bug.

Hi, when inside a case or a bug, you can see the contacts related to them, if you click the email address of one of them, it will bring up a mail composer pop-up (nice feature)

But I would expect the related to fields will be auto populated with the case or bug you have came from? Is this possible?

Assuming this is not a bug (you can check it by trying on the online demo to see if it is the same), you can try opening an Issue on GitHub with this suggestion.
