This was moved from TabHistoryPopupController's initializer to avoid accessing
|-popupContainer| in its initializer.  Also, it doesn't really make sense for
the initializer to call the fade in code.

+  CGPoint destination = CGPointMake(CGRectGetLeadingEdge(containerFrame),
+                                    CGRectGetMinY(containerFrame));
