Markdown details + mermaid not working togeter

example:

```mermaid graph LR A[1] --> B[2] --> C[3] ```

The HTML tag <details> seems to break the used Mermaid support. Usually it’s discouraged to add HTML to Markdown as it kills the whole purpose of this format.

all right, maybe i need chage my mind, Not divided into compressed content, but made into box sub-pages.

This also doesn’t work in HTML, so it’s not merely a Markdown issue nor is it a DEVONtech issue.

Thank you. The right answer
