[why and how]
This line was originally removed for a compliance issue, but then
reverted as it caused a fringe underflow case.
However, the addition of this line caused a underflow regression
when subVP is on, and it needs to be removed again. We plan to
fix subvp underflow and then re-add in this line. After that,
we will investigate what to do next for the compliance issue.
