           Summary: CSS clip-path is applied to the <svg> root element in
                    the view-box coordinates
           Product: WebKit
           Version: WebKit Nightly Build

test case

Open the attached test case.

Results: A 100x100 green box is displayed
Expected: A 250x250 green box is displayed

The CSS size of the <svg> root element is 400x400 but its view-box size is 200x200. The <svg> root element also has a clip-path: inset(0 150px 150px 0). This means 150 pixels from the right and from the bottom should be clipped to the 400x400 bounding box. And a 250x250 green box should be displayed.

The bug is the clipping is applied to the view-box rectangle. This leaves only 50x50 box. This box is displayed 100x100 because the local-to-parent transformation is 2:1.
