Uncaught TypeError: stop is not a function

[Smirow]

I got this error:

index.mjs:54 Uncaught TypeError: stop is not a function
    at index.mjs:54:17
    at behavior.ts:6:52

when a menu (dropdown) is unmounted while redirecting.
Seems like it has something to do with unsubscribing:

svelte-headlessui/packages/lib/src/lib/internal/behavior.ts

Lines 4 to 7 in f11d3ad

	export function applyBehaviors(node: HTMLElement, behaviors: Behavior[]) {
	const unsubscribes = behaviors.map(behavior => behavior(node))
	return () => unsubscribes.forEach(unsubscribe => unsubscribe())
	}

see sveltejs/svelte#4765 and sveltejs/svelte#8186

Maybe the error should be catched and silenced while waiting for the PR above to land, or finding a way to prevent these falsy unsubscribe?
