Understanding twoslash VFS, doing something wrong? missed something? #59
Description
As I have been progressing through stabilizing my new expressive-code-twoslash Expressive code plugin, one of the issues I've been facing is the inability to use the showEmit functions. It seems that the VFS is not being appended correctly, I've tried reading through the source of both shiki-twoslash as well as twoslash and it seems like this should be handled automatically by twoslash, but the only thing I seem to get is the error "unable to find file from virtual file system containing ." for any codeblock I try to enable showEmit on. Would appreciate any input that could help resolve this issue.
With EC:
Input:
```ts twoslash
// @showEmit
const level: string = 'Danger'
```Error:
## Cannot find the output file in the Twoslash VFS
Looking for index.js in the Twoslash vfs after compiling
Looked for" /home/native/Documents/Repos/EC-Plugins/docs/twoslash/index.js in the vfs - which contains .
