When we add absolute image url with preset having $, the css file will not load and throw exception from OOB code (com/adobe/granite/ui/clientlibs/script/Utils.java).
But by escaping $ we can overcome above issue and load the css file with preset correctly.
.load {
background:url("https://scene7.image.com/is/image/adobe/someimageutl?\$native\$");
}
