Summary
@ElePT reported that #13643 came back for other circuits, too. This essentially affects circuits that use operators as inputs, which have coefficients of complex types. This problem does not appear on
main, I assume #13278 removes the 0 complex component. We could still consider to add this safetyguard tomain, but there's no way to break it right now that I'm aware of.
