Hi,

Given the following code:

window.onerror = err => console.error('Error caught:', err);
foo

The error will be caught with these messages in my console:

Error caught: Script error
Uncaught ReferenceError: foo is not defined

However, given this:

var Raven = require('raven-js');
Raven.config('https://MY_SENTRY_DSN@app.getsentry.com/31423').install();
foo

The error won't be noticed at all by Raven:

Uncaught ReferenceError: foo is not defined

I can confirm that .install() sets the window.onerror handler by looking at it before and after .install() is run.

Running: Raven.captureException(new Error('This is an error!')); after .install() does, however, log;

Raven about to send:
> Object { ........

So it seems able to capture through captureException, but not through window.onerror, am I missing something here? (Using Chrome & Webpack with babel)

I get that ReferenceError is often something you might not wanna look at, but it's explicitly included in the docs So I'm a bit confused if Raven always ignores those errors.

Thank you!
