Comment:

 Okay, I've been thinking about that more and I came to the conclusion that
 this is strictly better for stable users as well compared to the current
 behavior: third party access would be mostly blocked anyway and seemingly
 randomly (form a user perspective) allowing access to the canvas data
 feels only weird (let alone the additional fingerprinting risk). So, I
 applied the patch to the stable, too: commit
 9a717351831505dff9b48b579353c043d8531fd6 has it.
