When double tapping the home button to show all currently open applications, the chrome app displays really old web pages and videos I had open. It even happens when the original tab was opened in incognito mode. It seems to happen more in landscape mode. When I quit the app, the information from my last browsing session, or any browsing session before that should not be visible.
