Key shortcuts register inconsistently

[tucnak]

This is about our Markdown dependency carta. It provides API for registering keyboard shortcuts, however there's a bug somewhere: either in our implementation, or in carta itself. The key binds are not registering consistently. So you would hit either of the "shortcuts," and nothing would happen.

The bug is seemingly random.

<script lang="ts">
	import type { Plugin, KeyboardShortcut } from "carta-md";
	import { Carta, Markdown, MarkdownEditor } from "carta-md";

	const enter: KeyboardShortcut = {
		id: "newline",
		combination: new Set(["enter"]),
		action: (input) => {
			input.insertAt(input.getCursorXY().right, "\n");
			input.update();
		},
	};
	const shiftEnter: KeyboardShortcut = {
		id: "submit",
		combination: new Set(["shift", "enter"]),
		action: (input) => dispatch("shutter", {}),
	};
	const shortcuts = (): Plugin => {
		return {
			shortcuts: [enter, shiftEnter],
		};
	};
	const carta = new Carta({
		sanitizer: DOMPurify.sanitize,
		disablePrefixes: true,
		disableTabOuts: true,
		extensions: [shortcuts()],
	});
</script>
