Polygon side tweening moves the 0 point on the middle of the created edge

[HastagGuigui]

Describe the bug
I'm working on a maths animation and there's a part involving a polygon with circles on each vertex, but tweening its side count results in the 0 point of getPointAtPercentage to being moved to the middle of the created edge.

To Reproduce

export default makeScene2D(function* (view) {
  let polygon = createRef<Polygon>();

	let side_count = createSignal(3);

	view.add(
		<Polygon ref={polygon} sides={()=>side_count()} lineWidth={8} stroke={"white"} size={512} y={200} opacity={0}/>
	)
	const cercles: Circle[] = [];
	polygon().add(
		<>
		{range(10).map(index => (
			<Circle 
				ref={makeRef(cercles, index)}
				position={() => polygon().getPointAtPercentage(index/side_count()).position}
				lineWidth={8}
				stroke={"white"}
				size={() => polygon().getPointAtPercentage(0).position.sub(
						polygon().getPointAtPercentage(1/side_count()).position).magnitude
				}
				opacity={() => index+0.9>=side_count() ? 0.0 : 1.0}
			>
			<Txt stroke={"black"} fill={"white"} lineWidth={4} fontSize={32}
				strokeFirst={true}
				text={() => "" + index/side_count()}/>
			</Circle>
		))}
		</>
	);
	yield* side_count(10, 2.0).wait(0.5).to(3, 2.0);


});

Expected behavior
I would have expected the 0 point to be on a vertex... not entirely sure actually, but I wish there was an easier way to get a polygon's points.

Additional context
Not sure if this is a bug or just jank

nevermind middle of the edge is intended it's just the other circles end up misaligned for a reason I don't know
