Is it possible that late events are processed before the window?

I have a job with event-time session window of 30 minutes.

I output late events to side output, where I have a tumbling processing time window of 30 minutes.

I observe that the late events are written to storage before the "main" events.

I wanted to know if it's normal before digging into the code and debugging the problem.

Thanks
