"Identifier 'self' has already been declared" when using @sveltejs/adapter-static

When trying to use the DataGrid with svelte 3 + sveltekit + adapter-static, I get this error:

> Using @sveltejs/adapter-static
> Identifier 'self' has already been declared
SyntaxError: Identifier 'self' has already been declared
at Loader.moduleStrategy (node:internal/modules/esm/translators:147:18)

I have fixed some Svelte SSR bugs in 3.0.9 so you may try again - if you see errors related to importing stylesheet use @activewidgets/svelte/bundle instead of the main package
