Summary Transparent PNGs lose alpha transparency when used in border-image

Reported 2008-05-20 16:49:11 PDT
Using WebKit Nightly Build r33943 (built on May 20th, 2008) on Mac OS X 10.5.2. Please see test case URL supplied. I applied a border-image to a DIV using -webkit-border-image, -khtml-border-image, and border-image (which isn't supported yet as far as I can tell). The PNG used for the border image has an alpha transparency (http://synaptictransmission.org/tests/img/border-image.png) which is rendered as white. Behavior expected: PNG should retain alpha transparency. Unable to test on other platforms.

The alpha channel in the image *is* being respected. The white that you're seeing is the background color of the div as specified in the CSS: div#container { background: #FFF; } Removing this line gives the expected result.
