Tween with duration 0 goes to NaN before becoming the target value

[TheSpeedM]

Describe the bug

Setting a Tween's options to { duration: 0 } sets the current value to NaN before setting the current value to the target value (which would be the desired behavior IMO).

Reproduction

https://svelte.dev/playground/300534b17dbd4ef2b5b72bfaa41672a7?version=5.16.1

Also view console output to see it becoming NaN before going to the actual value.

This issue can (probably) be fixed by porting these lines from the tweened implementation to Tween:

// snippet from tweened.set
if (duration === 0) {
	if (previous_task) {
		previous_task.abort();
		previous_task = null;
	}
	store.set((value = target_value));
	return Promise.resolve();
}
