Questions on the `owner` of using children() helper inside a context

I'm writing a component to show Toast.

The idea is to wrap the main component inside a ToastContext. It exposes a method success() to show a Toast for a successful action.
The shorten demo code is here https://playground.solidjs.com/anonymous/b8a41bdc-5569-41a0-86f5-d8fe42583d8f

- If I used

props.children

props.children

inside the ToastContext, then the component can

useContext

useContext

normally. We can see the context in the owner chain
- If I used children() helper inside the ToastContext, when the component use

useContext

useContext

, it results in a undefined context. There is no context in the owner chain

So:
- Why using children() helper does not keep the correct owner?
- How is an owner attached? I assume that as long as it is inside a JSX element, that JSX element is the owner, but it seems not to be the case here.
