This mostly coverts the target-offset check to use the updated spacing exception from the spec. However, going over this we did notice that we still might be off in determining the center of the bounding rect is. The code currently only looks at the largest target rect but we are thinking we need to take into account the bounding box for all target rects and center on that. Will leave that as a tech debt ticket for after 4.8 so we can get this merged in on time.

Another tech debt ticket that needs to be created is to update the target-size check to use the new getTargetSize function.

Closes: #3891

This function exists in IE11 (I've verified)

width: baseRect.right - baseRect.left

I thought it was weird that split rects works on DOMRects but then doesn't return one, which meant that doing splitRect(rect1, rect2).left would return undefined instead of the x value.

const nodeA = fixture.children[1];
const nodeB = fixture.children[3];
assert.closeTo(getOffset(nodeA, nodeB), 38, round);

Is the reason that this isn't exactly 40 because you're using buttons? This is why I used links when I wrote this originally, no min space, no padding, no border. I think you should use links so we get more consistent / predictable numbers.

It's because the distance between the centers of both buttons gets subtracted by the circle radius (50 - 12).
