Oleg Anastasyev commented on CASSANDRA-8013:
--------------------------------------------
Philo, yes, this could be the wider range thombstone case. However, just
removing assert could not work corectly. The subsequent for () {}, which
traverses both RTLs should account for more elements in replica's RTL than in
supersets and taking in account that single RT in superset can cover several of
replica's. Currently as i can see it does not.
