Dispatch custom events from loaded components

Hi, any way to connect createEventDispatcher in inner/loaded component to the outer world?

I have this in my `Options.svelte` component:

` import('./Select.svelte')} {element} on:selectionMade={selectionMade}>`

In this case `Select.svelte` dispatches selection event, and I'd like to handle it in `Options.svelte`, but the Loadable doesn't attach the handler to the inner/loaded Select.svelte.

Start with Options.svelte and the Loadable usage shown in the issue, then inspect how the loaded Select.svelte component handles the selectionMade event. Confirm the desired behavior by reproducing the example and verify that the outer handler receives the inner component's event.
