    hermanventer I know you mentioned you wanted to look at this issue, sorry if I’m stepping on your toes. Since I was blocked I thought a bit more about this issue and figured I was directionally correct, but the specific fix in #2459 was wrong. Also sorry for the PR churn. Thought I wasn’t going to come back to this issue.
    I think firstly, d and e should be comparing `x.value` to ±`0`. But I think these are then redundant, since c handles this for us. Sorry if I'm wrong on this!
