"Expand query not found" when it is nested in a callout or blockquote

[DimaReimann]

When you nest the code block in a callout or blockquote, it is not recognized and the Expand query not found notification is fired. Here is what I mean:

---

This works just fine:

```expander
path: "characters/"
$filename
```

---

I get the error message, because the plugin couldn't find the code block:

> ```expander
> path: "characters/"
> $filename
> ```

or

> [!note]
> ```expander
> path: "characters/"
> $filename
> ```
