Problem with collisions detection of views (KorGE)

Question

I create two SolirRect in random position and drag them on each other, but hitTestView() always return null

val list = mutableListOf<View>()

fun box() = solidRect(width / 10, height / 10, randColor()) {
    anchor(0.0, 0.0)
    scale(1.0)
    position(randPos())
    var dragOffsetX = 0.0
    var dragOffsetY = 0.0
    addUpdater {
        list.forEach {
            if (this != it) {
                println(
                    "Collision of ${list.indexOf(this)} " +
                    "with ${list.indexOf(it)} " +
                    "==> ${this.hitTestView(it, HitTestDirection.ANY) != null}")
            }
        }
    }
    onDown {
        dragOffsetX = this.x
        dragOffsetY = this.y
    }
    onMouseDrag {
        this@solidRect.x = it.dx + dragOffsetX
        this@solidRect.y = it.dy + dragOffsetY
    }
}
repeat(2) {
    box().let{
        list.add(it)
        if (list.indexOf(it) == 0) it.color = Colors.WHITE
    }
}

Output:

Collision of 1 with 0 ==> false
Collision of 0 with 1 ==> false
Collision of 1 with 0 ==> false
Collision of 0 with 1 ==> false
Collision of 1 with 0 ==> false
Collision of 0 with 1 ==> false
Collision of 1 with 0 ==> false

And output is like this independent of rectangels intesect with each other or not.
