following blending modes are rendered incorrectly: darken, color_burn, color_dodge, hard_light, soft_light, red, green, blue
Not overlapped part of the second rectangle are rendered black while it should keep the original color

Sample:

Stage {
    title: "Application title"
    scene: Scene {
        width: 625
        height: 402
        content: [
            Group {
clip: Rectangle { x:0 y:0 width:625 height:402 }
content: [
                    Group {
                        blendMode: BlendMode.DARKEN
                        content: [
                                Rectangle {
                                        x: 0
                                        y: 0
                                        width: 382 height: 244
                                        fill: Color.rgb(219,212,21)
                                },
                                Rectangle {
                                        x: 100
                                        y: 100
                                        width: 399 height: 231
                                        fill: Color.rgb(219,21,31)
                                },
                        ]
                },
            ]}
        ]
    }
}
