Setting cursor for window does not always behave as expected

[SebastianAigner]

Consider the following snippet:

fun main() = Window(title = "JFrame properties") {
    var crosshairCursor by remember { mutableStateOf(false) }
    onCommit(crosshairCursor) {
        val jFrame = AppManager.focusedWindow?.window
        jFrame?.let {
            it.cursor =
                if (crosshairCursor) Cursor.getPredefinedCursor(Cursor.CROSSHAIR_CURSOR) else Cursor.getDefaultCursor()
        }
    }
    MaterialTheme {
        Button(onClick = { crosshairCursor = !crosshairCursor }) {
            Text("Toggle crosshair cursor")
        }
    }
}

• Toggling the cursor via button press works fine
• Defocusing the window resets the cursor to the default cursor when re-entering the window.
• Refocusing the window via the dock icon uses the correct custom cursor again.
