Browser Compatibility --> Safari

What information was incorrect, unhelpful, or incomplete?

Since Safari 18, calling the get API with this form:
let gettingItem = browser.storage.local.get({ kitten: "no kitten", monster: "no monster", grapefruit: { name: "Grape Fruit", eats: "Water", }, });

Always return undefined.

What did you expect to see?
