Relative path is applied to data:image url

[mtscout6]

I am converting to webpack for my asset management and ran into a problem with the svg-gradient function. I was previously using less@1.7.4, but have recently upgraded to less@2.1.2.

I have a mixins.less file in a nested directory with:

.plan-gradient(@color){
  background: svg-gradient(to bottom,
    fade(@color, 0%) 0%,
    fade(@color, 5%) 60%,
    fade(@color, 10%) 70%,
    fade(@color, 15%) 73%,
    fade(@color, 20%) 75%,
    fade(@color, 25%) 80%,
    fade(@color, 30%) 85%,
    fade(@color, 35%) 88%,
    fade(@color, 40%) 90%,
    fade(@color, 45%) 95%,
    fade(@color, 50%) 100%
  );
}

The problem I have is that the folder in which the mixin resides is getting appended to within the url, like so:

background: url(oe-bootstrap/'data:image/svg+xml,base64,PD9.....');

I believe the offending code is in lib/less/tree/url.js Lines 26-31 since that if gaurd is not checking is the url is a data-url. I will follow up with a pull request unless there is a larger issue I am not seeing.

I originally reported this issue as webpack-contrib/less-loader#30.

The change in 94b3795 fixes my issue, but I don't know how to get all the tests green. There appears to be an issue around the base64 encoding option. I'm sure it's just a test setup issue, any suggestions on how to setup that test properly?
