Compilation Error

See original GitHub issue

Hi @Siilwyn,

after upgrading to the latest version I realized that there is a compilation error.

Failed to compile.
static/css/main.b90420c1.css from Css Minimizer plugin
TypeError: Cannot read property 'insertAfter' of undefined
    at Array.forEach (<anonymous>)

It occurs in the following code block:

  comments.forEach(node => {
    const pairedNode = node.pairedNode;
    node.comment.remove();
    pairedNode.parent['insert' + node.insertPosition](pairedNode, node.comment);
  });

It happens in case the pairedNode has no parent. Then pairedNode.parent['insert' + node.insertPosition](pairedNode, node.comment); fails.

For posterity this is odd behaviour of the sass-loader which css-minimizer-webpack-plugin is using in the CRA and other examples posted above. SCSS parsing is pretty weird especially when nesting nodes with special comments that it keeps even in compressed mode.

Fixed in version 6.1.4
