This is an HTML page served on a URL that ends with .md as if it was a markdown document, but it is not. github.com does not serve markdown files, it serves HTML files instead. You have to click on the raw button for that file which will take you to https://raw.githubusercontent.com/simov/markdown-syntax/main/mermaid.md instead. This is the origin that you have to enable, and the one that Markdown Viewer can operate on, because it serves the markdown document. You can read more about it in the examples section.
