Cannot set property length of [object Object] which has only a getter

[ghost]

I performed these steps:

git clone https://github.com/dtao/console-highlight.git cd console-highlight npm install node test.js

And this is my output:

/path/to/console-highlight/node_modules/jsdom/lib/jsdom/level1/core.js:553
      Array.prototype.splice.call(this._childNodes, refChildIndex, 0, newChild);
                             ^

What's going wrong?

Seeing the same thing on node 4.4.4

Still the same on node 6, but... as this is a very simple library (highlight.js + htmlout) I tried to do it myself and the problem persists... it's an htmlout fault.
