Why in this code the narrowing doesn’t work within the switch case in the function but it works when calling the function.

export enum Kind {
    A,
    B,
    C,
}

export interface KindMap {
    [Kind.A]: {
        a: string
    }
    [Kind.B]: {
        b: number
    }
    [Kind.C]: {
        c: string[]
    }
}

const func = <T extends Kind>(kind: T, info: KindMap[T]) => {
    switch (kind) {
        case Kind.A: {
            info.a // error, narrowing doesn't work here

            break
        }
    }
}

// Narrowing works correctly here
func(Kind.A, { a: 'string' })
func(Kind.B, { b: 1 })
func(Kind.C, { c: ['string'] })
