Another behaviour for retina images

Grav automatically injects sizes="100vw" for retina images.
As a result a browser stretches image on full page width. In some cases it may be useful, but in many other it works not well.

Is it possible to tell Grav to change this behaviour and use sizes=“{REAL IMAGE WIDTH}px”?

Currently, to make it looking in valid way, I use media query to set sizes manually. But it's really annoying.

Thanks
