[Bug] Test server in time-skipping mode does return userMetadata.summary

Bắt đầu bằng cách tái hiện ví dụ với test server ở chế độ time-skipping, đồng thời so sánh lịch sử workflow của nó với chế độ dev. Theo dõi việc xử lý summary từ workflow.execute_activity qua fetch_history_events đến user_metadata.summary. Hoàn thành khi summary xuất hiện trong HistoryEvent được trả về ở cả hai chế độ và các bài kiểm thử liên quan đều chạy thành công.

What are you really trying to do?

I want to leverage userMetadata.summary and show it in UI, and test the functionality.

Describe the bug

My tests fail when running tests with test server in time-skipping mode.
I am passing summary attribute when executing workflow and activities. Then I query workflow history I can see userMetadata.summary populated on the HistoryEvent when running in dev mode, but it is missing in time-skipping mode.

Minimal Reproduction

@workflow.defn
class WorkflowSample:

    @workflow.run
    async def run(self, name: str) -> list[str]:
        result = await workflow.execute_activity(ActivitySample.greeting, name, summary=f"Calculating greeting for {name}")
        return [result]

    async def get_payload_value(self, *args: Payload | None) -> str | None:
        decoded_summary = await self.data_converter.decode(non_empty_payloads(*args))
        if len(decoded_summary) == 0:
            return None
        return decoded_summary[0]

    async def get_summary(self, history_event: HistoryEvent) -> str | None:
        logger.debug("Getting summary for event %s", MessageToJson(history_event))
        return await self.get_payload_value(
            history_event.user_metadata.summary)
    
    async def run(self):
        async for event in workflow_handle.fetch_history_events(wait_new_event=wait_new_event):
            summary = await self.get_summary(event)
            print(summary)
