im going a bit tricky by comunicate with background by sendMessage and it works, still expecting better solution though

it doesn't seem to be a problem, it depends on the order of rendering and storage accessing.
storageDemo is a reactive value, if you want to get the latest value, use storage.local.get, if you want to subscribe to the latest value, use watch/watchEffect

I've found that useWebExtensionSettings is fundamentally flawed.

We are storing a bit larger json for caching purposes. Then when reading key.value it returns the default value, but if used with setTimeout(() => console.log(key.value), 1000) it works as there is enough time for the serializer to write the value.

Basically, useWebExtensionSettings() uses async calls (storage and serializer). Still, there is no way to use await as it isn't an async function itself, and top-level js wouldn't allow await use either.
