Vue version

3.3.4

Link to minimal reproduction

https://stackblitz.com/edit/github-pb6qhq?file=src%2Fcomponents%2Ftest-component.tsx

Steps to reproduce

just open the link,and see the console panel.

What is expected?

do not report the warnings ,and vnode.children should include all children,should not lose any useful child.

What is actually happening?

To render process will lose vnode child when and we use jsx syntax.

Logs:

[[Vue warn]: Hydration text mismatch:

Any additional comments?

there is another issue , i reported it on nuxt issue, there has more informations about the problem.

I found the cause of this problem.

// vnode missed other children in there,it just take one child.
// and node.data of server has full text content.
const vnode = optimized ? children[i] : children[i] = normalizeVNode(children[i]);

const Canary = /* @__PURE__ */ defineComponent(
  (props) => {
    return () =>
      createVNode('div', null, [
        // It has two children,one of TextVNode,one,one of raw string.
        // It just take 'createTextVNode('Your name is: ')' and ignore 'lee' when call hydrateChildren
        createVNode('span', null, [createTextVNode('Your name is: '), "lee"])
      ])
  },
  {
    name: 'Canary',
    props: {
      name: {
        type: String
      }
    }
  }
)
