Can I pass a rootNode to `nanohref`?

I am trying to mount a choo application in an "application shell" that is provided by a static site generator.

I would expect the routing behavior to be limited to the scope of choo's application host, yet `nanohref` will try to handle all anchors being clicked.

Looking at the `nanohref` docs, this behavior seems to be supported by passing a second `rootNode` argument to the `nanohref` function: https://github.com/choojs/nanohref#nanohrefhandlerlocation-rootnode

Looking at how choo itself is using `nanohref` it looks like passing a second argument is not intended: https://github.com/choojs/nanohref#nanohrefhandlerlocation-rootnode

This leads me to two questions:

1. Is it possible to achieve this behavior in some other way?
2. In case no, would you accept a PR that enables passing the application root to `nanohref` as well? In this case I have to admit I am slightly unsure how the API for this could even look like considering how there is basically zero surface area for options in choo.
