> {{TestVectorIfStatement}} generates interesting batches (injection of random repeating null column values and repeating non-null values) when evaluating the vectorized expressions. But the modification of random rows is done after the row mode is evaluated. Hence it is likely that comparison results will fail. I am not sure how its working in the first place.
