Problem with starting animation

I think there is some problem.

Problem occurs when I dynamically set the top and left style of some element then if I animate it with anime (the top value), it starts with the wrong value.

here’s my sample code:

<div id="testme" style="
	top: 1px;
	left: 1px;
	width: 100px;
	height: 100px;
	background-color: #000;
	position: fixed;
"></div>

document.getElementById('testme').style.top = '1vh';
anime({
	targets: '#testme',
	delay: 2000,
	top: {
		value: '+=50vh',
		duration: 2000
	}
});

without the anime function, #testme is positioned at the place I want it to be, but with the anime function, the top value was not the same. this only happens both for vh and vw units

Should be fixed in V3.

thank you for that response. It will help me solve my anime problem. though still it is weird how it changes the starting position.
