Using ETWReloggerTraceEventSource to gather events just from a certain time start/stop doesn't include stacks

I wanted to use the relogger to gather all events that occur within a certain start/stop time in a trace and then write that to a new etl file. What I found is that the stacks are not included (ex: CPU stacks).

using (var relogger = new ETWReloggerTraceEventSource(inputFileName, splitFileName))
{
relogger.AllEvents += delegate (TraceEvent data)
{
if (data.TimeStampRelativeMSec >= startTimeMS && data.TimeStampRelativeMSec <= endTimeMS)
{
relogger.WriteEvent(data);
}
};

            relogger.Process();
        };

Start with the ETWReloggerTraceEventSource usage shown in the issue and trace how relogger.WriteEvent handles events and their stacks during time filtering. Reproduce the reported case with CPU stacks, then verify that the newly written ETL retains those stacks while containing only events in the requested interval.
