The negation of these deltas caused a difference in the behavior of the E2E version of this benchmark as compared to the timeline version. In particular, the deltas were designed to perform 2 scrolls to the right and 2 to the left, but by negating the deltas the E2E version would start off with 2 animations of the "you've scrolled too far to the left" indicator which would skew the results.
