Not working with Responsive Images

The email address encoding plugin apparently is incorrectly assuming that any @ mentioned in the code is an email address, forcing me to disable it.

WordPress 4.4 introduced the new responsive images support. If it’s a Retina image, it will have a @2x suffix:

Track-Pedestals-02@2x.jpg
                  ^ -- The confused @ symbol

This causes the “encoded” email address to show up on the page, after the image looking like this.

600w" sizes="(max-width: 300px) 100vw, 300px" />

Search on that string and you will see sites with this issue.
