In case of row-level filters optimized out, i.e. converted to always true/false, it is possible for MergeTreeRangeReader to reuse incorrect statistics for the filter (countBytesInResultFilter()), and because of this it simply does not apply other filters, since it assume that this filter does not need to filter anything.
