Feature Request: Render contents that are inside `<details><summary>` block

[zendern]

Usecase

I have a markdown file that I want to transform to html using this library. When I have content that is inside of a <details> block it does not render correctly.

Example

Markdown File

## Inside Details/Summary block (DOES NOT RENDER)

<details>
<summary><b>My summary</b></summary>

Code to generate this html

import markdown

# read a file to a string
with open('example.md', 'r') as file:
    your_text_string = file.read()
    html = markdown.markdown(your_text_string, 
                             extensions=[
            "admonition",
            "markdown.extensions.tables",
            "markdown.extensions.fenced_code",
            "pymdownx.magiclink",
            "pymdownx.tilde",
            "sane_lists",
        ],)
    print(html)

Attempted fixes

I thought maybe if i wrapped the table that is inside of the in a tag it might render it. Tried <div> and <p> but neither helped. From looking at the code i think its likely due to details being listed as a Block level element and its to not be touched so rendering never happens.
