> CASSANDRA-14803 fixed an issue where reading legacy sstables in reverse could 
> return early in certain cases. It's also possible to get into this state with 
> current version sstables if there are 2 or more indexed blocks in a row that 
> only contain data for a dropped column. Post 14803, this will throw an 
> exception instead of returning an incomplete response, but it should just 
> continue reading like it does for legacy sstables
