Currently a collapsible section looks like this

  <summary>Click me</summary>
  
  ### Heading
  1. Foo
  2. Bar
     * Baz
     * Qux

  ### Some Code
  ```js
  function logSomething(something) {
    console.log('Something', something);
  }
  ```
</details>

Expected Behavior

But it should look/behave like this

Thank you for the issue. This is in our ToDos, but we can't handle right now.

I just learned that its actually not a specific markdown feature but rather a feature of HTML.
