Import results in "ReferenceError: window is not defined"

There's no check for if window exists before withObserver.js uses it.

Though this is a client only lib so if you are doing something like server side rendering code split and async load the section with this using something like System.import

Me too. Ctrl+C + V from first line in npmjs.com and results this error.

I guess it's just a matter of doing if (typeof window !== 'undefined) {...}
