This demonstrates a failure when using require-trusted-types-for 'script' in CSP during dev.

Note the CSP being set in vite.config.js. Start up the app using npm run dev, open the console, and you'll see something like:

This document requires 'TrustedHTML' assignment.
Uncaught TypeError: Failed to set the 'innerHTML' property on 'Element': This document requires 'TrustedHTML' assignment.
    at updateStyle (client.ts:367:22)
    at style.css:4:1

And the app will not load.
