compare different divs with the same image

[zambolip]

Hi all,
I found this problem:
The same element is defined by a class name in DEV environment, and another class name in PRODUCTION.
Since there are a different urls, I've created 2 branch ( the difference is only about the baseUrl and the element class name, of course) in order to compare the different urls as written in documentation
The image snapshot is the same, but Percy see them as two different images and does not compare them
