Custom Element loads intermitently

[jame5cross]

Describe the bug

Custom Elements don't appear to be working. I have tried locally and the custom element occassionally appear when saving the +page.svelte file, or navigating between pages in the quickstart demo but does not appear on page refresh. Reproduction below does not seem to work at all.

Reproduction

https://stackblitz.com/edit/sveltejs-kit-template-default-x2vhbq?file=src%2Froutes%2F%2Bpage.svelte

I have added to +page.svelte. Also added the customElements dependencies in svelte.config.js and MyButton.svelte
