I am currently trying to figure out why certain ATL stuff isn't working properly, and comparing the same programme running on Windows and Wine. While I've not yet been able to figure out the actual bug keeping the components from responding correctly, this difference in behaviour stood out immediately, and it could conceivably be a problem if a programme uses the `FindWindow` call to look for the AtlAxWin window by name (and that is what I did in my minimal testcase). With this minor change (which also matches the normal `WM_CREATE` idiom in Win32), Wine matches the behaviour I've observed on Windows 10. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10860#note_139455
