+We cannot remove events and properties that are happen to also exist 
+in base, even if we just call the base methods. The reason is that we 
+must exactly match the Microsoft defined events and properties. In 
+the case of Label, Microsoft defines these events and properties new 
+and sets different attributes for them. These attributes allow the 
+properties and events to be hidden if you use a GUI-Designer (like 
+Visual Studio). It is not possible to change attributes for inherited 
+methods, so they need to define them anew. As for the overriden 
+methods, MS might be doing something in them for the specific class 
+were we don't need to because we have a different implementation, but 
+still, for binary compatibility we need to match the API.
+The change you made to LabelTest to make the test not fail is not 
+correct, too. While your patch will make the test pass, the test as 
+it is shows that our Label.TabStop is not defaulting to the right 
+value (we default to true, thus, when it's set to true the changed 
+event is not fired). MS defaults TabStop to false for Label, 
+therefore, when setting to true it will fire the event. The bug was 
+in Label, not in the test.
+I fixed Label to properly pass those tests now, I did take your 
+improvement using EventArgs.Empty instead of new EventArgs().
+Thanks for the bug report.
