Steps to reproduce the problem:
1. Make your viewport narrow.
2. Go to http://srcset.salcode.com/
3. Gradually increase the width of your viewport. The page progressively loads in larger versions of the image, as needed.

What is the expected behavior?
In the DOM Tree, DevTools highlights which version of the image is being displayed.

What went wrong?
Feature does not exist.

Did this work before? No

This is a feature request.

Currently the only ways to figure this out are to highlight the element in the DOM Tree and evaluate $0.currentSrc, or to dig through the Properties tab.
