I've found that "empty" object tag causes a major issue in Webkit's for Windows fallback content rendering. The fallback content is simply not rendered at all. The issue was found on http://forum.mediaswiat.pl/ I've made minimal test case for this issue. Steps to reproduce 1) Go to a page: http://bugs.blaut.biz/webkit/object-fallback-content.htm 2) Notice blank page. Expected result: Webkit should render: "The text is a fallback content and should be visible" Actual result: Webkit renders nothing.
