## Inline in Shortcode

Inline:{{< highlight emacs "hl_inline=true" >}}(message "this highlight shortcode"){{< /highlight >}}:End.
Inline Unknown:{{< highlight foo "hl_inline=true" >}}(message "this highlight shortcode"){{< /highlight >}}:End.

## Inline in code block

Not sure if this makes sense, but add a test for it:

§§§bash {hl_inline=true}
(message "highlight me")
§§§

## HighlightCodeBlock in hook

§§§html
(message "highlight me 2")
§§§

## Unknown lexer

§§§foo {hl_inline=true}
(message "highlight me 3")
§§§
