Currently, any failed request to the source Wiki will result in the target Wikibase entering an error state. This behavior is the case even in non-critical situations (e.g.such as displaying property labels on the item page) and in situations where an edit is attempted and fails because accessing the source wiki is impossible.
When loading entity page and displaying federated property not possible,If displaying federated properties is not possible when loading the entity page due to a failed call to the source Wiki, we should display a partial version of the entity page and an error message explaining the situation to the user: "Statements about this item are temporarily unavailable due to a failed request to the federation source Wiki. we should display a message indicating the data is unavailable due to the failed call to source Wiki.Please refresh the page."
We've decided to go for the following: the entity title and perhaps label in the current language isshould be displayed, in addition to the error message (just an error page, avoids page rendering complexity and fun)
**Note**My connection to the source Wiki is unavailable
`When` I load an item page containing statements with federated properties
`Then` A partial entity page is displayed containing the item name, label in the current language, and an error message
**Note**: this needs to be made testable in the test system for product verification to take place
