Handling of activation in the generic implementation of standard renderers was broken since r62589 which stopped calling their Activate() method. Restore it by introducing a special WXOnActivate() replacing it (but clearly marked as private and implementation-only) and calling it instead. Closes #11460. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@64654 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
