// while the page loaded properly. Ideally the "ts_devserver" would allow us to opt-in for
// just returning a 200 status code, but the devserver is intended to be kept manually, so
// we manually filter this error before ensuring there are no console errors.
// TODO: This is a current limitation of using the "ts_devserver" with Angular routing.
// Tracked with: TOOL-629
