Oh, I don't think we support the reference syntax.

There are two elements in the testcase both using the same syntax for clip-path. It works on the <div> but not the <video>.

The <div> one will be software-painted, the <video> one will be on GraphicsLayer.

The video referenced by the testcase no longer exists, so the testcase is not valid.

Here's a fresh repro along with a workaround: https://jsfiddle.net/yjbanov/nh9jzLba/35/ Setting style.width and style.height to 100% fixes the issue. Remove the lines that set it and Safari will stop showing the video.
