[Typescript BUG] _persist is missing in type State but required in PersistPartial

[subrapak]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch [email protected] for the project I'm working on.

TLDR; when passing initialState to a persisted reducer, typescript expects a _persist key to be defined in your initial state (which it doesn't need to be).

Typescript Error: Type 'XState' is not assignable to type 'XState & PersistPartial'. Property '_persist' is missing in type 'XState' but required in type 'PersistPartial'

Without it, I was getting a typescript issue when passing initial state into a persisted reducer. This is because the persisted reducer was typed as Reducer<WorkoutNowState & PersistPartial, AnyAction>, and PersistPartial requires a _persist key to be defined in the reducer, which I obviously didn't want to define in the initial state.

Looks like this issue was solved in 2018 here, but seems to have crept back in: https://github.com/rt2zz/redux-persist/pull/725

Here is the diff that solved my problem:
