Describe the Bug
When you add any JSX Comment between the <!doctype html> and the tag like this:
<!doctype html>
{/* Comment */}
<html lang="en">
<head>
<meta charset="UTF-8" />the and tag are missing from the output file after running astro build. The file just starts with the doctype and then the tag after the tag like this:
<!DOCTYPE html>
<meta charset="UTF-8">The issue is present with Bun v1.31.1 and Node.JS v25.1.0 (npm 11.6.2).
What's the expected result?
The outputted HTML should include the missing tags like this:
<!DOCTYPE html>
<html lang="en" data-astro-cid-sckkx6r4>
<head>
<meta charset="UTF-8">Link to Minimal Reproducible Example
