My editor has file which has following html code as source.

<!-- playground-hide -->
<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Sample</title>
</head>

<body>
    <!-- playground-hide-end -->
    <button>Some visible content>
    <!-- playground-hide -->
    <script type="module" src="main.js"></script>
</body>

</html>
<!-- playground-hide-end -->

If I do cmd + a, then cmd+v the whole page content is pasted even if only the <button>Some visible content> is the only displayed content inside the editor.

I've noticed this as well folded or hidden content is included in the pasteable content when selecting all in the codemirror instance.

Perhaps there's a way to hook into CodeMirror's paste event to filter out the hidden content.
