LineSegment.intersection(with:) not working properly

[nazariyg]

Confirming that LineSegment.intersection(with:) may return nil for valid intersection cases:

let s1 = LineSegment(a: .init(x: 187.50440979003906, y: 543.5147094726562), b: .init(x: 333.1461486816406, y: -109.8446273803711))
let s2 = LineSegment(a: .init(x: 0, y: 0), b: .init(x: 375, y: 0))
let intersection = s1.intersection(with: s2) // nil

Should not be nil, as the two segments are intersecting at a point:
