Do you need to clean up in useObservable?

@crimx Question about cleanup

if i have code like this with an intermediate observable

	const chatResponseDebounced$ = useObservable(() => {
		// normalize tokens
		const chatResponseSplit$ = chatResponse$.pipe(
			buffer(chatResponse$.pipe(filter((token) => /[ \t]/.test(token)))),
			mergeMap((tokens) => {
				const result = tokens.join('');
				return result
					.split('\n')
					.flatMap((part) => [part, '\n'])
					.slice(0, -1);
			}),
			filter((word) => {
				return word !== '' && word !== null;
			}),
			share()
		);

		// emit tokens compatible with markdown renderer
		return chatResponseSplit$.pipe(
			buffer(chatResponseSplit$.pipe(filter((token) => !/[\n\s]/.test(token) || /\w[^#_*~`\n-]/.test(token)))),
			mergeMap((tokens) => {
				const result = tokens.join('');
				return result
					.split('\n')
					.flatMap((part) => [part, '\n'])
					.slice(0, -1);
			}),
			filter((word) => {
				return word !== '' && word !== null;
			})
		);
	});

do i need to clean up chatResponseSplit$ somehow?

Generally you don't need to.

There is an edge case metioned in #123 that certain hot operators like shareReplay rely on upstream complete signal to auto-unsubscribe. So if you keep chatResponseDebounced$ for a long time while switching downstreams that includes operators like shareReplay, staled downstreams may not be properly auto-released until chatResponseDebounced$ is garbage collected.
