Pasting a copied control event handler can create a suffixed window method

In Objo Studio, copying a control event handler such as a Canvas Paint method and pasting it onto another control event could create a normal Window method with a generated suffix, such as Canvas4_Paint1, instead of applying the paste to the selected target event handler.

Expected behaviour: pasting onto a compatible control or control event should create or update the matching target handler, for example Canvas6_Paint or the selected Canvas4_Paint, and keep it under the control's Events section.
