[Interest] Is QML globalCompositeOperation incorrect?

[程梁]

Hi,
I have tested globalCompositeOperation of Context2D in Qt 5.3.1 but I found this is different from behavior of HTML5 canvas. I think this is incorrect accord with documents.
I have attached these two screenshots. Is QML incorrect or my code is incorrect?
QML  HTML5
