[🐞] New child added cannot access to parent context

[jcfauchet]

Which component is affected?

Qwik Runtime

Describe the bug

We noticed a bug by rendering a new element under a parent with context.
Qwik try to render the new element, it throws an error telling us he cannot access to the parent context :

Here is the corresponding code :

Parent wrapper

import { component$, createContextId, Slot,  useContextProvider, useStore } from "@builder.io/qwik";

export const WrapperContext = createContextId<{
  active: boolean
}>('FLOWBITE_QWIK_WRAPPER_CONTEXT')


export const Wrapper = component$(() => {
  useContextProvider(WrapperContext, useStore({ active: false }))

  return <div>
    <Slot />
  </div>
})

Child item added dynamically

import { component$, Slot, useContext } from "@builder.io/qwik";
import { WrapperContext } from "./Wrapper";

export const Child = component$(() =>  {
  const context = useContext(WrapperContext)

  return <div data-active={context.active}>
    <Slot />
  </div>
})

Page adding Child item to Wrapper :

import { component$, useStore } from "@builder.io/qwik";
import { Child } from "~/components/Test/Child";
import { Wrapper } from "~/components/Test/Wrapper";

export default component$(() => {
  const childs = useStore([1, 2, 3]);

  return (
    <>
      <button onClick$={() => {
        childs.push(childs.length + 1);
      }}>
        Add child
      </button>
      <Wrapper>
        {childs.map((child) => (
          <Child key={child}>{child}</Child>
        ))}
      </Wrapper>
    </>
  );
});
