The <video> element (which is displaying an image) in LayoutTests/fast/replaced/border-radius-clip.html is not clipped by the -webkit-border-radius CSS applied to the element.
* STEPS TO REPRODUCE
1. Launch Safari or a WebKit nightly build.
2. Open: LayoutTests/fast/replaced/border-radius-clip.html
The <video> element is not clipped.
I assume the layout test was working when it was checked in.
See Bug 21789 for the original fix.

Not a regression as the <video> element was never clipped in r41952 either.
Probably regressed when we enabled hardware video.
A bug was filed at webcompat.com related to this, but for unprefixed border-radius (which probably doesn't matter in practice):

The webcompat.com is about Chrome, which doesn't use WebKit. The codepen works in the current version of Safari, so marking this bug as closed.
