See:

https://bugs.webkit.org/show_bug.cgi?id=150271

http://code.google.com/p/chromium/issues/detail?id=544290

The testcase from the WebKit bug could be easily made into a reftest.

調査方針: The issue provides a WebKit bug link (https://bugs.webkit.org/show bug.cgi?id=150271) and a Chromium bug link (http://code.google.com/p/chromium/issues/detail?id=544290) with a testcase (https://bugs.webkit.org/attachment.cgi?id=263749&action=edit). The request is to convert that testcase into a reftest for the wpt repository. Look at existing reftests in the wpt repository for reference, particularly in the css/ directory. Ensure the reftest includes both the test and reference files. No additional maintainer clarification needed; the scope is well defined.
