On an test I received for this lesson. Kwiziq says "it is extraordinary that something happened" translates in French to "il est extraordinaire que quelque chose se soit passé"
My thoughts: "it is extraordinary that something happened" seems to refer to a certain factual event , already in the past, which is not a suggestion, wish, etc. , so why use subjonctif ? This clearly is not the same as "It is important for something to happen..."
