I don't have any clear commit ids you could cherry-pick. The only suggestion I can give at this point is to please forget about 1.12.2. It's not even the last stable update in 1.12.x series. A lot of things have been fixed since then :/ Same for 1.16.2 actually, multiple updates in the 1.16 branch happened with lots of different fixes. And we've had 2 additional major stable releases since then: 1.18 (along with multiple updates in that series) and 1.20.0 just last week. -- Aleksander
