Missing code block highlighting (same background color as the slide)

[eltix]

When inserting code blocks in the Markdown document, the syntax highlighting works but the code block itself is not highlighted.
Below is a sample Markdown document to illustrate my issue:

---

Start a new project with the template

$ sudo apt-get install cookiecutter
$ cookiecutter someurl foo
$ cd foo && ls
hackage/
tools/

data MyData q =
  MyData
  { name    :: String
  , content :: q
  }

class LatexShowable a
  where toLatex :: a -> String

f :: (LatexShowable a) => a -> IO ()
f = print . toLatex

---

Here is the Google slide generated with

md2gslides slides.md --style atom-one-dark

As you can see, the code blocks do not stand out from the rest of the slide the way the code blocks in this very issue do (by being included in a rectangle with a different background color). Is this something that can be fixed?

I've tried with other --style options (github, tomorrow-night, etc.) but the highlighting of the code block itself is the same.

Other than that, thanks for the great tool! I really like being able to put syntax highlighted code in my slides.
