Just to be clear, if I understand correctly, this is a pure revert of
44bda4b7d26e and as such it reintroduces the problem solved by that
If your solution turns out to be better, that's great, but it would be
nice to avoid the bisection hole of reintroducing the problem, then
fixing it again later.
