Wrong embla-carousel-svelte init event types

[davidjerleke]

Bug is related to

• embla-carousel-svelte

Embla Carousel version

• v7.1.0

Describe the bug

• When using the on:init event with TypeScript, the following error shows:

Argument of type '{ class: string; "on:init": (event: CustomEvent<EmblaCarouselType>) => void; }' is not assignable to parameter of type 'Omit<Omit<HTMLAttributes<HTMLDivElement>

The problem can be solved by adding the following to a d.ts file:

declare namespace svelteHTML {
  interface HTMLAttributes<T> {
    'on:emblaInit'?: (event: any) => any
  }
}

...which is very hacky and not desired.

Expected behavior

• The event shouldn't trigger any TypeScript error and use the ActionReturn<Parameter, Attributes> so the tooling picks up the correct types.

Will be released with v8.0.0-rc02.
