Parser will extract script tags in script tags and bork the parent script

Sounds wild, I know. And it's a bit of an edge case.
But if you have a script tag in an element definition, and then in that script tag you have a string that contains an open or close "", the parser gets eager to start extracting scripts.

Here's a sample `<my-element>` that will blow up in the browser -- server render works, or at least doesn't throw

```js
export default function ({ html }) {
return html`
<h1 class="text4 font-mono">my-element</h1>

<script>
console.log('start.')

// this string will trip up the parser
const someHTML2 = '<script>window.$$ = "$$";'

console.log('done.')

`
}
```

and here's a screenshot of what is rendered
