--- Comment #5 from [e-mail] ---
I created merge request:
https://gitlab.winehq.org/wine/wine/-/merge_requests/6737

didn't add extra nmhdr.code comparisons because I don't know what they do in
windows and wine's toolbar already handles and doesn't forward 0xfffffc7a =
PGN_CALCSIZE, 0xfffffc7b = PGN_SCROLL, 0xfffffdee = TTN_GETDISPINFOW

also wine handles and doesn't forward 0xfffffdf8 = TTN_GETDISPINFOA:

case TTN_GETDISPINFOA:
        FIXME("TTN_GETDISPINFOA - should not be received; please report\n");
        return 0;

which windows xp professional x64 edition service pack 2 and windows 7 ultimate
service pack 1 just forward
