Dexie.on.close
Syntax
db.on("close", () => console.log("db was closed"));
Description
The "close" event occurs if database is forcibly closed from external action. From dexie@4.1.0, this event is also fired as a CustomEvent when db.close() is called explicitely or implicitely and not just when forcibly closed from outside.
