Comment:

 As previously noted in comment:14:ticket:48606, the current implementation
 fails on formats like `F y`, where `Май 19` ("May 19" in Russian) is
 assumed to be 19th day of May and declined, while it's actually the 19th
 year (as in 2019).

 Since `wp_maybe_decline_date()` is no longer just a filter on `date_i18n`
 and is now called directly from `wp_date()` as a result of [45901], we can
 pass the date format to it to determine the necessity of replacement,
 instead of trying to guess the format without any context.

 [attachment:"48934.diff"] implements that and adds a new test case.
