Broken? Firefox issue?

I found this package today and it seems to do exactly what I want. Except… I can’t get it to work.

I installed it via npm, put a basic <input type="search"> and set it up like so

var h = holmes({
                input: 'input[type=search]',
                find: 'label',
                class: {
                    visible: 'highlight',
                    hidden: 'hidden'
                },
                hiddenAttr: true,
                mark: true
            });

Nothing appears to happen, and nothing shows up in console either.

The demo page doesn’t work properly for me either. As I type I get TypeError: t.textContent.toLowerCase(...).includes is not a function errors in the console.

These may be separate issues, I’m not sure.

Now, that is what I call quality support!
