> {{LazyDownConversionRecordsTest}} fails when using {{zlib-ng}} since it assumes the *v1 records* should be *smaller or equal to* the size of {*}v2{*}. This may *not be correct* anymore because the *longer match size* used by {{zlib-ng}} can cause the *v1 format* to not be compressed as well as the original zlib.
