some tests triggered an exception in KiUserCallbackDispatcher, but it's displayed back to user with ERR on seh channel, which is silenced during gitlab pipeline. Maybe this should still be displayed (eg. with MESSAGE)
FYI, https://gitlab.winehq.org/wine/wine/-/merge_requests/3454 allows you to disable exception-silencing behavior in window procedures. I think this is very useful in both tests and real apps.
