Markdown HMR sometimes does not work

[troubleshooting section]: https://iles-docs.netlify.app/faqs/troubleshooting

- [x] I have read the __[troubleshooting section]__ before opening an issue.
- [x] I have tried upgrading `iles` and `vite`.

### Description 📖

When the Markdown `` is after some kind (I'm not sure which) of island, its HMR does not work.

### Reproduction 🐞

https://github.com/ouuan/iles-issue-232-reproduction

Run `pnpm dev` and edit `src/pages/index.mdx`, only the random number changes, and the Markdown content does not change.

If the island and the `` are in a reversed order, or `client:load` is removed, or the prop is a fixed number, the HMR will work.

The real issue is that the HMR in my blog does not work after https://github.com/ouuan/iles-blog/commit/863909c49d4b0948ddc894ade4e2bdb2019fd74d, and I managed to get the above minimal reproduction.
