Option `collectWindowErrors` is mentioned in https://github.com/getsentry/raven-js/issues/91 and seems to be implemented in the code. However it is not mentioned in the documentation https://docs.sentry.io/clients/javascript/config/ nor it is supported by RavenOptions in https://github.com/getsentry/raven-js/blob/master/typescript/raven.d.ts#L10 * https://github.com/getsentry/raven-js/blob/master/src/raven.js#L59 * https://github.com/getsentry/raven-js/blob/master/src/raven.js#L187
