Markdown no longer shows the proper compiled page

I use the compiled Markdown to provide documentation for Datamancer, a plugin for JetBrains IDEs (PyCharm, IntelliJ, etc) which provides dbt support.

## Bug

1. Go to https://docs.getdbt.com/docs/build/documentation?version=1.11&name=Core
2. Click "Copy as Markdown" (or go to https://docs.getdbt.com/docs/build/documentation.md)
3. We see:

```
import CopilotBeta from '/snippets/_dbt-copilot-avail.md';

Good documentation for your dbt models will help downstream consumers discover and understand the datasets you curate for them.
dbt provides a way to generate documentation for your dbt project and render it as a website.

```

and:

### FAQs

```
etc.

## Expected result

The full page.

## When did this break?

Unsure. I swear it use to work.
