Test Case

Information about environment

4.6.0 in Chrome

Steps to reproduce

Create a group that is clipped via ClipPath and contains Text that has a Shadow with an offset. The rendering messes up and hides the entire canvas background. It is ok if the shadow offset is 0. You can see in my example/test case that the canvas should be red, but is showing up white. Change the offsetX and offsetY to 0 and it will render correctly as red.
