Group cull method not working as expected

[calebfoss]

In this example, in frame 1 cull() removes the above, below, and left sprites but not the sprite to the right of the canvas. group.includes(spriteRight) returns true for the first two frames and then false.

let group;
let spriteAbove, spriteBelow, spriteLeft, spriteRight;

function setup() {
  new Canvas(400, 400);
  group = new Group();
  spriteAbove = new Sprite(0, -1, 100);
  spriteBelow = new Sprite(0, height + 1, 100);
  spriteLeft = new Sprite(-1, 0, 100);
  spriteRight = new Sprite(width + 1, 0, 100);

  group.push(spriteAbove);
  group.push(spriteBelow);
  group.push(spriteLeft);
  group.push(spriteRight);
}

function draw() {
  background(220);
  group.cull(0);
  console.log(`FRAME ${frameCount}
Above: ${group.includes(spriteAbove)}
Below: ${group.includes(spriteAbove)}
Left: ${group.includes(spriteLeft)}
Right: ${group.includes(spriteRight)}`);
  noLoop();
}
function mousePressed() {
  redraw();
}

What's going on?

I just learned that for of loops do not automatically compensate for if a sprite is removed! That's why it removed only removed two sprites the first frame. Just fixed this in v3.6.9!
