Related to T148657. When only a cached or saved version of a page is available because a network request fails, show a snackbar to the user.
From @Kaartic:
I just wanted to give a suggestion. It would be useful if a //message// is displayed to the user that informs him that the page has been loaded from cache. Something like
>The page has been loaded from the cache.
or
>Showing cached version.
This would be useful because the user would be aware that the page has been loaded from cache and not a //refreshed one//. Some users **may not be aware** that it is a cached version.
Firefox browser shows a message when an offline version of the page is loaded.

The message is just a temporary one, displayed for a few seconds. This would help the user to know whether the content is loaded from //cache// or has been //refreshed//.
