image-set with image in base64 format cause error

[maoxiaoke]

Describe the bug

When using image-set, it can use image in base64, like this:

  cursor: --webkit-image-set(
    url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAQAAAC1+jfqAAAAL0lEQVQoz2NgCD3x//9/BhBYBWdhgFVAiVW4JBFKGIa4AqD0//9D3pt4I4tAdAMAHTQ/j5Zom30AAAAASUVORK5CYII=)
          1x,
        url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAQAAADZc7J/AAAAz0lEQVRIx2NgYGBY/R8I/vx5eelX3n82IJ9FxGf6tksvf/8FiTMQAcAGQMDvSwu09abffY8QYSAScNk45G198eX//yev73/4///701eh//kZSARckrNBRvz//+8+6ZohwCzjGNjdgQxkAg7B9WADeBjIBqtJCbhRA0YNoIkBSNmaPEMoNmA0FkYNoFKhapJ6FGyAH3nauaSmPfwI0v/3OukVi0CIZ+F25KrtYcx/CTIy0e+rC7R1Z4KMICVTQQ14feVXIbR695u14+Ir4gwAAD49E54wc1kWAAAAAElFTkSuQmCC)
          2x
      )
      5 8,
    text;

But after running npm run build, you may get an error. This only happens in the latest version 2.9.8。

I think this pr #7874 broke this behavior.
