It is not possible to drag a URL on HTML inspector and drop it on a new tab on Chrome. Please open the provided URL, then open the inspector, and try to drag the img src URL to a new tab. Chrome will search <img src="https://www.webkit.org/images/icon-gold.png"> but IMO user is expecting opening the URL in new tab. It will also happening on data:text/html;charset=utf-8,<a href="https://www.webkit.org/images/icon-gold.png">Link</a> when you want drag and drop href to new tab.
As a workaround you could right click and select "Open link in new tab" in context menu.
