If this issue only occurs in one browser, which browser is a problem?

No response

Describe the Bug

All shiki transformers that use the meta part of a code block don't work.

E.g.: transformerMetaHighlight and twoslash

```ts {1,3-4} <- this part after the "ts"
```ts twoslash <- this part after the "ts"

What's the expected result?

Using those transformers should enable twoslash or highlight the lines per the transformers documentation.
