On bootstrap Angular calls addEventListener for popState but on Destroy it never calls removeEventListener

[ernestlv]

In a SPA sometimes you bootstrap an Angular application then upon browser navigation you have to destroy the current application and bootstrap a new Angular application. All in the sampe page.

In this line, angular register a listener for the "popstate" and "hashchange" event using addEventListener:

https://github.com/angular/angular/blob/master/packages/platform-browser/src/browser/location/browser_platform_location.ts#L45

However, after I destroyed the original application angular never call removeEventListener. Thus when I bootstrap the second application in my SPA the browser fires the new listeners for the "popstate" and "haschange" events plus the original ones.

The number of listeners keeps increasing if I keep navigating back and ford between this applications.

Desired result:

Remove "popstate" and "hashchange" events thru removeEnvetListener when the application is destroyed.
