I think it's a bit more complicated. Returning partial content seems to be a valid response according to the spec. But the Content-Range and Content-Length headers shown in Chrome DevTools are clearly wrong, they should indicate what is actually returned. So I still think there's a small bug in how Chrome handles this, but solving this bug wouldn't help the author, as it's still the responsibility of OpenDAL to fix handling partial content on their side.
