"twitching" bug from the very first version of Qt Quick

This a bug from many years, but I produced an example only now. Go over to https://github.com/user1095108/qtnanosvg and compile the example and execute it. Then, without moving the application window, resize it randomly. Return the cursor into the window area and move it, click on the buttons, without depressing. You should see the tiger "twitch", which I believe comes from a delayed width, height property update (i.e. a delayed widthChanged, heightChanged signal being delivered).
