[Smush Pro] Conflict with Master Slider plugin

We’ve discovered that there is an odd issue with Smush pro and Master Slider plugins; when Smush CDN is enabled.

The slider images are still served from our server, even though they are indeed in <img> tags and not CSS background images.

Also, when the Automtic Resizing option is enabled in Smush CDN, the images disappear from the slides and seem to have a max-width of 1px inlined for the sizes.

This was confirmed by Patrick during a live chat and attached screenshots are from his test site.
