Describe the bug

Built-in components and animation in code blocks do not work in version 51.0.0 and above.
I tested the same slide.md with version 0.50.0, 0.51.0-beta.1, and 0.51.0-beta.4 and all the functionality mentioned seems to work fine.

Minimal reproduction

Steps to reproduce the behavior:

1. Start slidev sli.dev/new.
2. Replace slides.md with

Current slide number: <SlideCurrentNo />.

```{all|1|2|2-3|all}
line 1
line 2
line 3
```

3. Run pnpm install && npm run dev.
4. Try interact with the slide. This stepping through slide should highlight all lines, line 1, line 2, then line 2+3, then back to all lines.
5. Try changing slidev's version in package.json to "51.0.0", and repeat the step 3 and 4 again. The slide number will not show up and steping through the slide will not change any thing in the code block.

Environment

• Slidev version: 51.0.0 (with bug), 0.50.0, 0.51.0-beta.1, and 0.51.0-beta.4 (without bug)

• Browser: Brave

• OS: macos, stackblitz.

• If you are using Slidev globally (i.e. npx slidev or npm i -g slidev), please try to reproduce the issue in a local project (i.e. npm create slidev@latest).
