Loader fails on SVG definition rules with URL values

[BarakChamo]

The loader seems to break when .less files include references to SVG definitions. I'm using the markers in the styles because I don't want to mess with the charting library I'm using but the less loader breaks on the URL.

Marker definition:

<defs>
    <marker id="line-marker">
        <circle cx="6" cy="6" r="5"></circle>
    </marker>
</defs>

Marker use:

path.nv-line {
    marker-mid: url('#line-marker');
}

Is there a way of ignoring some URL values in the .less files or another way to prevent the loader from failing?

I realized that this is a css-loader issue and I'm moving the issue there
