Is this necessary? If so, it'd be nice to document why.

+    WebRemoteFrame* webRemoteFrame = remoteClient.frame();

+
+    LocalFrame* localFrame = toLocalFrame(toCoreFrame(mainFrame()));
+    RemoteFrame* remoteFrame = toRemoteFrame(toCoreFrame(webRemoteFrame));
+
+    // Attempt to close the window, which should fail as it isn't opened
+    // by a script.
+    remoteFrame->domWindow()->close(localFrame->document());
+    EXPECT_FALSE(remoteClient.closed());
+
+    // Marking it as opened by a script should now allow it to be closed.
+    remoteFrame->page()->setOpenedByDOM();
+    remoteFrame->domWindow()->close(localFrame->document());
