I've found an annoying issue with the CSS border-radius property in Safari.
My blockquotes are styled with a border only on the left-hand side - not an issue - but when I then apply a border-radius to the element the right-hand corners get a slight border applied along the curve. Here's an example using w3school's tryit:
The same styling in Chrome doesn't present the extra artifacts:
I have specified the individual border colours separately and even tried using the individual radius properties (e.g: border-top-right-radius) to no avail.
