It's done for 'compatibility' - presumably with WebKit-apps rather than other browsers. Adobe says that flash requires a width and height parameter in the OBJECT element and these are missing in the site reporting the issue (http://helpx.adobe.com/flash/kb/flash-object-embed-tag-attributes.html). So this looks like a combination of WebKit-specific behaviour and invalid code from the reporter. Is the bug invalid?
