While working on T246606, we discovered that a federated property used to make a statement will initially link to a non-existent local property page until the item page is reloaded. The property label should link to the property page on the source Wiki immediately after a statement is saved instead.
Given I am creating a statement using a federated property
When I click "save" to publish the statement
Then the property label is displayed in the statement, including language fallbacks
And the label is linked to the Wikidata property page
