Bug Report: Copy as Markdown does not copy the doc contents

[Eric162]

Report

Tell us what went wrong and how we can reproduce it. Include URLs or screenshots if helpful.

The Copy as Markdown button downloads the md file, not the actual contents. E.g. on https://posthog.com/docs/llm-analytics/installation/vercel-ai

it just downloads the mdx file contents instead of the text on the page.

# Vercel AI LLM analytics installation

import { VercelAIInstallation } from 'onboarding/llm-analytics/vercel-ai.tsx'
import { OnboardingContentWrapper } from 'components/Docs/OnboardingContentWrapper'
<OnboardingContentWrapper snippets={{ NotableGenerationProperties }}>
    <VercelAIInstallation />
</OnboardingContentWrapper>
