Rehydrating a Map with integers as keys turns them into strings.

[schumannd]

I can imagine this has to do with using react natives AsyncStorage, which only saves strings.

We should find a way to save the type of the key before saving them to async storage. Once saved there I think it is not possible to find out the type again.

Maybe this is an issue with all integers?

Easily reproducible by creating a @persist Map<number, whatever>, then saving something in it, rehydrating, and its key has changed from int to string.

I have a similar issue:

@observable public Categories: Map<string, boolean>;

which is a becomes a and don't have the value after hydrating..
