Describe the bug

1. Collapsible section with <details> tag does not work or not rendered as expected.
2. Gollum does not show a collapsible section but instead it ignores the tag. I tried various iterations but could not get it to work.
3. E.g. https://gist.github.com/joyrexus/16041f2426450e73f5df9391f7f7ae5f

To Reproduce
I put the following in one of my markdown files for testing purposes

<details>
    <summary>click here</summary>
    
1. this
1. should
    1. be
    1. a folded
    1. list

</details>

Expected behavior
The tag should be rendered as a collapsible section, just like on this Github website:
