Describe the bug
I would like to develop web components with Svelte. For this I have set "compilerOptions" to true.
svelte.config.js

...
const config = {
	...,
	compilerOptions: {
		// enable web component mode
		customElement: true
	}
};
...

After my changes the App is broken and nothing works anymore.

Logs

Uncaught TypeError: Cannot read property 'page' of undefined
Uncaught (in promise) TypeError: Illegal constructor

To Reproduce

  1. Create n new SvelteKit Projekt and enable "customElement" mode.
  2. Add <svelte:options tag="component-NAME_HERE"/> to all components.
  3. Start the dev server.
  4. The App is broken and the console is full of errors.
