When multiple box-shadows are declared on an element with border-radius, if one of the shadows has a "spread" distance defined, it affects the border radius that the other shadows render. Attaching an example. Observed in Google Chrome 11.0.696.68 (WebKit 534.24).
Created attachment 93334 [details] testcase reproducing the behavior
This does not repro in Safari WebKit on Mac using r86200. Maybe a Chrome bug?
I can reproduce in Safari r81878, but not by r83253. Tried a nightly of Chrome and it is resolved there as well. So it looks like it got fixed in WebKit at some point and is making its way to release. Thanks!
