Cookies of private mode are deleted only after the app is closed, not when user leaves private mode

[Riccardo Padovani]

Go (in private mode) to a site that requires login (like launchpad.net).
Do login, navigate, all works well.
Exit private mode.
Go in 'clear' mode to the site you logged in private mode, you shouldn't be logged in (right).
Go in private mode again.
Go to launchpad.net (or whatever): you're logged in.
Exit browser
Go in private mode
Go to launchpad.net: you aren't logged in (good)

I expect cookies are deleted when I leave private mode, not when I close the browser.

I’m guessing cookies for incognito webviews are stored in memory, but they should probably be wiped when the last incognito webview is deleted.
