Shows ugliness when border is added to border-radius image

Image corner rounding in Safari 4.0.3 is still wrong. This is related to https://bugs.webkit.org/show_bug.cgi?id=24880, which has two requests (mine and another) to be reopened. Maybe a new bug is more appropriate:


While an image without a border now rounds nicely, if I add a border things get
icky. The image is getting clipped to the outside of the border, rather than
the inside. This means either the image still has square corners showing (if
the border is thicker than the radius) or the border gets drawn over by the
image (if the border is thinner than the radius).

I'd expect the image edge to always follow the inside of the border, as the
workaround in the OP's link shows. (Caveat: I'm not a CSS guru, so maybe the
standard requires clipping to the outside edge of the border. I sure hope not,
as this is terribly ugly.)

This bug still hasn't been fixed. I would suggest its title to be changed to "Replaced content gets clipped according to border box".

The spec clearly dictates that replaced content should be clipped according to the content box: "The content of replaced elements is always trimmed to the content edge curve." (http://www.w3.org/TR/css3-background/#corner-clipping)

IE9 and Firefox 4 both get this right.

I can confirm this issue, which Opera 11.51 is also rendering wrong. See http://rivierenlandzakelijk.nl/ (border around the map) for an example.

Chrome: 15.0.874.6 Canary build
