Yes, windows does have more handled notifications.

There are notifications that don't get forwarded.

There are notifications that `nmhdr->code` overwritten and get forwarded.

Not all notifications have `nmhdr->code` that is equal to a macro in mingw-w64's [commctrl.h](https://github.com/mingw-w64/mingw-w64/blob/e3a3dc588a6358bda826934d3adfeaa3...) and [prsht.h](https://github.com/mingw-w64/mingw-w64/blob/e3a3dc588a6358bda826934d3adfeaa3...).
