#9856: wxSizer::Replace( size_t, wxSizerItem *) doesn't call SetContainingSizer

src/common/sizer.cpp: wxSizer::Replace( size_t old, wxSizerItem *newitem ) doesn't call SetContainingSizer when handles wxSizerItem referring to windows. Look at wxSizer::Replace( wxWindow *, wxWindow *, bool ) that properly calls SetContainingSizer.
