Buttons hang when redirecting page

When you receive a push notification that contains a data with the name of a page to be redirected. When you click on the notification this.push.on ('notification') method is called (line 217), the redirect is done successfully, but the page seems to freeze because I click on other buttons and nothing happens. If the device changes orientation, the action of the button clicked before is called. Can anyone have any idea what that might be? link
