Sorry, I didn't say it clearly, but this patch still applies.
ï¼·hen a consumer re-balance occurs and
**FirstPollOffsetStrategy#EARLIEST/LATEST**, the retained partition wouldn't
use the committed offset to resume but use the -2 / -1 offset, as I observed,
so this is reason why the comment (`leave the acked offsets as they were to
resume where it left off`) doesn't apply.
