> Thats a bit silly. I don't have Safari here, so I can't test it on my own. But if I apply a clip mask to an object, it should mask the object with all it's content, including the background. Why should the background get removed? Or if we see the object without it's background, the background in your example should be solid red and and the text would be "filled" with a red-green-red gradient.

Well... on Safari the stripes are white, not red :). This is because the red background is applied first and then the IN operator (the "op" parameter of RenderBoxModelObject::paintFillLayerExtended) I talked about removes some of the text with respect to the text mask. The composition operation doesn't "know" there is a red background and just keeps some of the content with respect to the mask image (the gradient box in our case) and removes the other content (the gradient stripes).
