bug: initialState function not working for deep object mutations

• I have searched for existing issues that already report this problem, without success.

Stencil Store Version

2.0.4

Stencil Version

3.0.0

Current Behavior

According to the documentation, the initialState property can be a function that returns the actual initial state. This is useful for cases where we have deep objects that mutate, as the library is unable to track those changes otherwise. However, I have found that this feature does not seem to be working as expected.
Also, the typing is not correct - the exported state is treated as a function in case I pass function to the createStore

Expected Behavior

When using a function as the initialState, changes to deep objects should be reactive and properly tracked and updated by the library.

Steps to Reproduce

1. Create store with the createStore function and pass a function which is return with the initialState according to the docs.
2. Observe that changes to the deep object are not being tracked as expected.

Just wanted to up on this Ticket. I checked the code and it seems there's a mis-typing in the createStore function. View here
The defaultState has been typed as T but is passed to the createObservableMap which is expecting a Invocable<T> compare with this line.
I could open a PR to fix the typings if necessary.
