autoBind option don't bind flows automatically

[OldGraff]

Intended outcome:
Similary to actions, flows can be bound by default using autoBind option. — said in the documentation
makeAutoObservable(this, { }, { autoBind: true }); — not working b/c lose context

Actual outcome:
makeAutoObservable(this, { logout: flow.bound }, { autoBind: true }); — working don't lose context

How to reproduce the issue:

Try to autoBind generator and it lose context
