"<script>" in string literal in <script> element in HTML fails to parse #21150
Description
Describe the bug
In my index.html file, I have a script element in the <head>. Inside of that, I have a string literal that includes "</script>". This throws the following error:
[vite] (client) Pre-transform error: Failed to parse source for import analysis because the content contains invalid JS syntax. You may need to install appropriate plugins to handle the .js file format, or if it's an asset, add "**/*.js" to `assetsInclude` in your configuration.
Plugin: vite:import-analysis
Reproduction
https://stackblitz.com/edit/vitejs-vite-u2lf5z82?file=index.html
Steps to reproduce
Open the Stackblitz.
The only change from the boilerplate is the addition of this in the index.html file-
<script type="module">
// This line breaks
const string = `</script>`;
</script>
