Marp preview had used
<div id="marp-vscode">and<style id="marp-vscode-style">to show the preview.The default Markdown preview by VS Code will automatically generate ID from the heading content, so this line (generates
<h1 id="marp-vscode">) can break Markdown preview easily:# marp-vscodeI've updated to use
#__marp-vscodeand#__marp-vscode-styleinstead.__prefix is mostly safe in preview because it will not be generated as heading slug.
