@blegat before I merge this, take a look at v1.40.2...master and see if you're happy.

MOA failure looks like a spurious change due to the last release of HiGHS. I'll take a look.

(Also note that the checklist includes a solver-tests.yml run. I run it for every release)

MOA failure is a presolve bug in HiGHS scaling issue in MOA: jump-dev/MultiObjectiveAlgorithms.jl#104
