Type errors in `svelte2tsx`

Describe the bug

Hello, I'm getting multiple type errors in svelte2tsx after disabling skipLibCheck:

/home/user/project/node_modules/svelte2tsx/svelte-jsx.d.ts:49:95
Error: Type 'Property' cannot be used to index type 'IntrinsicElements'.
    Omit<
      Omit<import('svelte/elements').SvelteHTMLElements[Property], keyof EventsWithColon<Omit<svelte.JSX.IntrinsicElements[Property & string], svelte.JSX.AttributeNames>>> & EventsWithColon<Omit<svelte.JSX.IntrinsicElements[Property & string], svelte.JSX.AttributeNames>>,
      keyof Override

/home/user/project/node_modules/svelte2tsx/svelte-jsx.d.ts:60:13
Error: Interface 'IntrinsicElements' incorrectly extends interface 'SvelteHTMLElements'.
  The types of ''svelte:window'['on:devicemotion']' are incompatible between these types.
    Type 'EventHandler<DeviceMotionEvent, HTMLElement> | null | undefined' is not assignable to type 'EventHandler<DeviceMotionEvent, Element> | null | undefined'.
      Type 'EventHandler<DeviceMotionEvent, HTMLElement>' is not assignable to type 'EventHandler<DeviceMotionEvent, Element>'.
        Types of parameters 'event' and 'event' are incompatible.
          Type 'DeviceMotionEvent & { currentTarget: EventTarget & Element; }' is not assignable to type 'DeviceMotionEvent & { currentTarget: EventTarget & HTMLElement; }'.
            Type 'DeviceMotionEvent & { currentTarget: EventTarget & Element; }' is not assignable to type '{ currentTarget: EventTarget & HTMLElement; }'.
              Types of property 'currentTarget' are incompatible.
                Type 'EventTarget & Element' is not assignable to type 'EventTarget & HTMLElement'.
                  Type 'EventTarget & Element' is missing the following properties from type 'HTMLElement': accessKey, accessKeyLabel, autocapitalize, dir, and 123 more.
  // the following type construct makes sure that we can use the new typings while maintaining backwards-compatibility in case someone enhanced the old typings
  interface IntrinsicElements extends Omit<RemoveIndex<svelte.JSX.IntrinsicElements>, keyof RemoveIndex<import('svelte/elements').SvelteHTMLElements>> {
    a: HTMLProps<'a', HTMLAttributes>;


/home/user/project/node_modules/svelte2tsx/svelte-jsx.d.ts:246:5
Error: Duplicate index signature for type 'string'.

    [name: string]: { [name: string]: any };
  }

Pushed a commit that helps silence this, release pending. But ultimately this is a misuage of svelte2tsx within Svelte Material UI. I opened hperrin/svelte-material-ui#665 for that.

Great, thanks for both!
