[Bug]: Loading external js script in svelte story

[stantonius]

Describe the bug

Hey team

Awesome library - thanks for all of your hard work!

I am running into an issue where I cannot load an external js script in my Svelte stories. I have followed the guidelines that show how to incorporate an external js script here and I can see this script included in the body of the iframe. However regardless of what I try, the Dropdown component in the Codesandbox (and my local machine) only works in Sveltekit but not in the story.

Note that I am using a combination of Skeleton UI and Flowbite (the standard library, not the dedicated Svelte library as this conflicts with Skeleton UI) as css styling libraries, which are both TailwindCSS based.

I tried to specifically include the flowbite js script (Flowbite cdn docs here) in svelte using the <svelte:head> tag but this didn't work. I have tried to wrap the component within the story in my Svelte layout in hopes the js would "filter down" as it does when running Svelte on its own, but this didn't work either.

I understand (the theory, not necessarily the details) that svelte does SSR as much as possible, so maybe it has something to do with this?

To Reproduce

I created a Codesandbox here - I think Sveltekit should open automatically to show a basic Dropdown, which works. However when you run storybook and look at the Dropdown story, nothing happens.

This has all of the same setup I am using, including the preview-body.html that I can see referenced within the iframe.
