Special comment in index.html causes incorrect injection

Describe the bug

To keep it simple, my index.html has a commented version of the code preceeding the code. E.g.

<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Housing Search App</title>
  </head>
  <body>
    <div id="root"></div>
    <script type="module" src="/src/index.jsx"></script>
  </body>
</html> -->

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Housing Search App</title>
  </head>
  <body>
    <div id="root"></div>
    <script type="module" src="/src/main.jsx"></script>
  </body>
</html>

I execute npm run build, and the module scripts I expect in dist/index.html are not present in the code for this file, but rather the scripts are injected into the comment. View dist/index.html for confirmation.
