The message test doesn't confirm that this is a correct solution.

I tested the sequence from WM_KILLFOCUS twice in dlls/user32/tests/msg.c.

static const struct message SetFocusButtonSeq[] =
{
    { WM_KILLFOCUS, sent },
    { CB_GETCOMBOBOXINFO, sent|optional },/* Windows 2000 */
    { 0x0167, sent|optional },/* Undocumented message. Sent on all versions except Windows 2000 */
    { WM_LBUTTONUP, sent|defwinproc },
    { WM_COMMAND, sent|parent|wparam, MAKEWPARAM(ID_COMBOBOX, CBN_SELENDCANCEL) },
    { EM_SETSEL, sent|defwinproc|wparam|lparam, 0, 0 },
    { WM_CTLCOLOREDIT, sent|defwinproc|optional },/* Not sent on W2000, XP or Server 2003 */
    { WM_CTLCOLOREDIT, sent|parent|optional },/* Not sent on W2000, XP or Server 2003 */
    { WM_COMMAND, sent|parent|wparam, MAKEWPARAM(ID_COMBOBOX, CBN_KILLFOCUS) },
    { WM_CTLCOLORBTN, sent|parent },
    { 0 }
};

static const struct message SetFocusButtonSeq2[] =
{
    { WM_KILLFOCUS, sent },
    { CB_GETCOMBOBOXINFO, sent|optional },/* Windows 2000 */
    { 0x0167, sent|optional },/* Undocumented message. Sent on all versions except Windows 2000 */
    { WM_LBUTTONUP, sent|defwinproc },
    { WM_COMMAND, sent|parent|wparam, MAKEWPARAM(ID_COMBOBOX, CBN_SELENDCANCEL) },
    { EM_SETSEL, sent|defwinproc|wparam|lparam, 0, 0 },
    { WM_CTLCOLOREDIT, sent|defwinproc },
    { WM_CTLCOLOREDIT, sent|parent },
    { WM_COMMAND, sent|parent|wparam, MAKEWPARAM(ID_COMBOBOX, CBN_KILLFOCUS) },
    { WM_CTLCOLORBTN, sent|parent },
    { 0 }
};

In both sequences, the expected value of EM_SETSEL is 0, 0.

Perhaps I'm not understanding what you mean in this case.

I mean that adding a SendMessage() call should fix the message sequence
if that's how it's supposed to work, and as a result you would remove TRUE
as an indicator of todo_wine for fixed sequences.
