That is very unfortunate to our testing process, as we want to make sure we don't introduce regressions ourselves. Instead of blindly accepting any failures, I took the path of looking at the test changes upstream. Clean cherry picks were not always possible, so, in some cases, I decided to go failure by failure, and fixing up the test with a change that was already present upstream. That will make cherry picks even harder in the future, but that's the cost of maintaining something upstream doesn't care about.
