Hi Maciej,
I filed the Radar bug because of failure of the attached layout test. I am going to add this layout test in the patch for this bug.

Starting from snow leopard, the npapi plugin is run under "WebKitPluginHost.app" process, and WebKit relies on the allowPopups flag passed from "WebKitPluginHost.app" RPC to control to whether block the popups initiated by plugin or not. 
When debugging with XCode, I found the allowPopups flags from "WebKitPluginHost.app" was not right. (Please take a look the attached debug snapshot).
I hope my explanation answers your question.
