Incorrect type generation for components without script tag

[bluwy]

Describe the bug
If a component doesn't have a script tag or has nothing in a script tag, the generated type class doesn't extend from SvelteComponentTyped. This causes the vscode extension to complain "cannot be used as JSX component" (Screenshot below).

To Reproduce
Steps to reproduce the behavior:

I'm using svelte2tsx emitDts() to generate the types.

Given: Section.svelte

<section class="my-6">
	<slot />
</section>

Output:: Section.svelte.d.ts

/** @typedef {typeof __propDef.props}  SectionProps */
/** @typedef {typeof __propDef.events}  SectionEvents */
/** @typedef {typeof __propDef.slots}  SectionSlots */
export default class Section {
}
export type SectionProps = typeof __propDef.props;
export type SectionEvents = typeof __propDef.events;
export type SectionSlots = typeof __propDef.slots;
declare const __propDef: {
    props: {};
    events: {
        [evt: string]: CustomEvent<any>;
    };
    slots: {
        default: {};
    };
};
export {};

Expected behavior

/** @typedef {typeof __propDef.props}  SectionProps */
/** @typedef {typeof __propDef.events}  SectionEvents */
/** @typedef {typeof __propDef.slots}  SectionSlots */
- export default class Section {
+ export default class Section extends SvelteComponentTyped<{
+ }, {
+  ​[evt: string]: CustomEvent<any>;
+ }, {
+  default: {};
​+ }> {
}
export type SectionProps = typeof __propDef.props;
export type SectionEvents = typeof __propDef.events;
export type SectionSlots = typeof __propDef.slots;
+ import { SvelteComponentTyped } from "svelte";
declare const __propDef: {
    props: {};
    events: {
        [evt: string]: CustomEvent<any>;
    };
    slots: {
        default: {};
    };
};
export {};

Screenshots

System (please complete the following information):

• OS: Ubuntu 21.04
• IDE:VSCode
• Plugin/Package: svelte2tsx

Additional context
I'm able to reproduce with local repo of language-tools. Trying to figure out why.

Did some digging, seems like svelte2tsx generates this for dts mode:

rt { SvelteComponentTyped } from "svelte"

declare function __sveltets_1_createSvelteComponentTyped<Props, Events, Slots>(
    render: {props: Props, events: Events, slots: Slots }
): SvelteComponentConstructor<SvelteComponentTyped<Props, Events, Slots>,Svelte2TsxComponentConstructorParameters<Props>>;

<></>;function render() {
<><button onclick={undefined}><slot /></button></>
return { props: {}, slots: {'default': {}}, getters: {}, events: {'click':__sveltets_1_mapElementEvent('click')} }}
const __propDef = __sveltets_1_partial(__sveltets_1_with_any_event(render()));
/** @typedef {typeof __propDef.props}  InputProps */
/** @typedef {typeof __propDef.events}  InputEvents */
/** @typedef {typeof __propDef.slots}  InputSlots */

export default class Input extends __sveltets_1_createSvelteComponentTyped(__sveltets_1_partial(__sveltets_1_with_any_event(render()))) {
}

The initial impo is gone.
