Bug 33333

This test cannot pass on platforms other than Mac because the NP plugin is a child of the page rather than the webview on those platforms. The test is intended to cater for cases where a window is closed but -[webview close] is not called by the plugin - Mac experienced a regression where you could close the window and the plugin would continue displaying because the plugin did not close the webview. When a window is closed on non-Mac platforms the page is deleted and the plugin destroyed, so the message logged by the plugin in the test reaches a deleted object. In the case of Qt, because the object is (being) deleted the log message from the plugin arrives in the QWebPage's implementation of javascriptConsoleMessage() (which does nothing by default) rather than in that of DRT's derived class WebPage (which writes to stdout). It's pure chance that the memory has not been overwritten at that point so it would not be correct to alter QWebpage to cater for it. (Note that this behaviour only occurs in the DRT anyway because the test plugin has logDestroy property).
