Not all computed return values are replaced by assignments when multiple code paths.

[saabi]

<script>
	import * as constants from './constants.js';

	export default {
		computed: {
			style: ({ divider }) => {
				const group = divider.parent;

				const x = group.getLeft();
				const y = group.getTop();
				const w = group.getWidth();
				const h = group.getHeight();

				if (divider.type === 'horizontal') {
					return `left: ${x * 100}%; top: ${(y + divider.position * h) * 100}%; width: ${w * 100}%`;
				} else {
					return `top: ${y * 100}%; left: ${(x + divider.position * w) * 100}%; height: ${h * 100}%`;
				}
			}
		}
	};
</script>

is converted to:

<script>
	import * as constants from './constants.js';

	export let divider;

	export let style;
	$: {
		const group = divider.parent;

		const x = group.getLeft();
		const y = group.getTop();
		const w = group.getWidth();
		const h = group.getHeight();

		if (divider.type === 'horizontal') {
			style = `left: ${x * 100}%; top: ${(y + divider.position * h) * 100}%; width: ${w * 100}%`;
		} else {
			return `top: ${y * 100}%; left: ${(x + divider.position * w) * 100}%; height: ${h * 100}%`;
		}
	}
</script>
