How likely are real events to come in and interfere with this?

At least in this circumstance, I'd imagine the likelihood is probably low. It will only pass EVENT_OBJECT_FOCUS for this particular event, and in that case it'd have to be fired by the system due to this specific HWND gaining focus. In all my testbot runs I have not seen this happen yet.
I guess we could potentially gate this somehow so that if it doesn't match a combo of hwnd/obj_id it isn't checked, or just remove the check all together. Or, only do: ``` hr = IProxyProviderWinEventSink_AddAutomationEvent(event_sink, This->win_event_handler_data.responder_prov, This->win_event_handler_data.responder_event); ok(hr == S_OK, "Unexpected hr %#lx.\n", hr); ``` if it matches our expected WinEvent.

I see there's at least a 0.5 second window for this. Would it be possible to set up the window such that the system won't focus it?

The 0.5 second window is when we do not expect a WinEvent to be passed through. I'm thinking it might make sense to filter by specific WinEvent parameters that we're listening for, e.g if we do `NotifyWinEvent` and we don't expect this particular WinEvent to be passed through to the `IProxyProviderWinEventHandler::RespondToWinEvent` method, we could fail the test if that specific set of parameters is delivered. The main point is to test whether or not a specific set of WinEvent parameters will result in `RespondToWinEvent` being invoked.
So, if we did that, and the system fired a WinEvent that was delivered and didn't meet our expected parameters, it'd just be ignored. The only issue with that would be if Windows somehow managed to send a duplicate. I guess in that circumstance, we could potentially clear the expected parameters once `RespondToWinEvent` is invoked/calls `AddAutomationEvent`.
I'll look into this further on Monday.

I haven't seen it happen in practice, but in theory:
- `uia_stop_event_thread()` is called and sets the the thread reference count to 0. - This clears the `event_thread` structure and posts `WM_UIA_EVENT_THREAD_STOP` to the event thread's message queue. - WinEvents are still in the queue and need to be processed before `WM_UIA_EVENT_THREAD_STOP` is encountered. In this case, these will need to be discarded.
