Wine 8.5: Bug is still present

dinput_main.c has comment for problem call MsgWaitForMultipleObjectsEx:
void check_dinput_events(void)
{
    /* Windows does not do that, but our current implementation of winex11
     * requires periodic event polling to forward events to the wineserver.
     *
     * We have to call this function from multiple places, because:
     * - some games do not explicitly poll for mouse events
     *   (for example Culpa Innata)
     * - some games only poll the device, and neither keyboard nor mouse
     *   (for example Civilization: Call to Power 2)
     * - some games do not explicitly poll for keyboard events
     *   (for example Morrowind in its key binding page)
     */
    MsgWaitForMultipleObjectsEx(0, NULL, 0, QS_ALLINPUT, 0);
