Test `scope` not working with svelte 3.35.0

On master when running the test with svelte 3.35.0 (not happening with 3.34.0)

scope

  throw new AssertionError(obj);

Do you mean Svelte instead of Prettier?

Ho yeah you're right 😅 I fix it

I think this is a bug in Svelte. The AST that's generated for <Component2><div slot='foo' let:blah={blah2}>{blah1}{blah2}</div></Component2> (the part of the test that's failing) looks like it's missing some stuff in 3.35.0. It's just

{
  start: 0,
  end: 78,
  type: 'Fragment',
  children: [
    {
      start: 0,
      end: 78,
      type: 'InlineComponent',
      name: 'Component2',
      attributes: [],
      children: []
    }
  ]
}

in 3.35.0 - none of the children of Component2 are present.

Svelte 3.36.0 has been released, which fixes the AST bug that was causing this.
