svelte2tsx outputs wrong invalid TSX (return value -> events)

[hgiesel]

Describe the bug
svelte2tsx outputs invalid tsx given the example.

To Reproduce
Parse the following code with svelte2tsx:

<script>
    import { createEventDispatcher } from "svelte";

    const dispatch = createEventDispatcher();
    dispatch("mount", { input });
</script>

<input on:focus />

It also works, if you do it in the Svelte2tsx REPL. There is a comma missing in the return value, in the events property.

Expected behavior
Output valid tsx.

System (please complete the following information):

• OS: macOS, Browser
• Plugin/Package: svelte2tsx, I use the npm package directly

Thanks for the report! Off topic question: What's your use case for using svelte2tsx directly?

The Ankitects team uses it for using Svelte + TypeScript with Bazel, usage here.
