click not possible throught overlaying view

In Korge 2 it's not possible to click throught an overlaying view even if mouseEnabled is set to false.
This is a basic sample for reproducing:

```
suspend fun main() = Korge(width = 512, height = 512, bgcolor = Colors["#2b2b2b"]) {
val rectFront = SolidRect(100, 100, Colors.GREEN)
rectFront.apply {
mouseEnabled = false
}
val rectBack = SolidRect(300, 300, Colors.ALICEBLUE)
rectBack.apply {
mouse {
up {
color = if (color == Colors.ALICEBLUE) Colors.CHOCOLATE
else Colors.ALICEBLUE
}
}
}
addChild(rectBack)
addChild(rectFront)
}
```

I expect the rectBack changing its color even if I'm clicking on rectFront, but it's not.

Start by running the Kotlin reproduction in the issue and inspect Korge's mouse event handling for mouseEnabled. Verify whether clicks on the front SolidRect reach the back SolidRect, then confirm the back rectangle changes color when the overlay is disabled.
