Codeblock render error in the @css-blocks/webpack documentation

Hey,

The codeblock section for the rewriter under the webpack docs does not appear to be rendering properly:

Start in the webpack documentation and locate the rewriter codeblock section described in the issue. Compare its source with the rendered page and the attached screenshot, then verify that the corrected codeblock renders properly in the documentation.
