(Testbed) Box position offset when not using piqnt editor

[armput]

I'm learning planck and I'm using the AIJS Editor and whenever I run the testbed, it offsets boxes by about (-0.3, 0.3).

The dot and the body are both at (0, 0) but you can see that the box is offset a tiny bit.

Here's the code:

const { World, Testbed, Box, Vec2 } = planck;
planck.testbed(function(testbed) {
    const world = new World();

    let box = world.createDynamicBody(Vec2(0, 0));
    box.createFixture(Box(2, 8), 2);
    
    console.log(box.getPosition());

    testbed.step = function() {
        let pos = box.getPosition();
        testbed.drawCircle({x: pos.x, y: pos.y}, 0, '#fff');
    }

    return world;
});

I went over to the piqnt.com editor and it works as expected but in the other editors I've tried boxes are offset.

Is there any way to fix this issue more permanently than offsetting the position?

[Update]: So apparently this also applies to polygons.

Thanks for reporting!

I'm rewriting the testbed, I will fix this one as well.

Currently the testbed in this repo is slightly different from the implementation in piqnt.com, after rewrite they will share the same code.

I fixed this in v1.3.0.
