We looked into taking a screenshot right before leaving the
BrowserFragment, however this call will always fail since it's
non-blocking (we never want it to be blocking too), and we will never
receive a screenshot when a session is detached from an EngineView
before the callback is complete.
In Fenix, we can nicely evade this by taking a screenshot when click
the tabs tray icon, which is where you would want to see the most
up-to-date thumbnail of the tab and also does not leave the
BrowserFragment as well.
