Bug ID: 55451
           Summary: Application gets WM_IME_COMPOSITION without getting
                    WM_IME_STARTCOMPOSITION before
           Product: Wine
           Version: 8.13
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs@winehq.org

This program can reproduce the problem
On wine 8.8 there isn't such a problem.
On wine >=8.9 <=8.13, when the user uses input method to input something, the
program gets some WM_IME_SETCONTEXT (0x281) messages first, and then gets
WM_IME_NOTIFY (0x282, with IMN_WINE_SET_COMP_STRING 0x10), and then gets
WM_IME_COMPOSITION (0x10f). There isn't a WM_IME_STARTCOMPOSITION (0x10d) sent
before WM_IME_COMPOSITION. And after WM_IME_COMPOSITION, there isn't
WM_IME_ENDCOMPOSITION (0x10e) either.
