I think this has the same root cause as #16984.
I ran all 3 tests, and the difference in expected vs actual output was very alike to the one in #16984.
So I applied the patch from #16984 (comment) and the issues are all gone now.
I'm marking this as a duplicate, but keeping it open until Dmitry figured out the details of the issue.

Fixed via 03bb112 together with #16984

@dstogov Awesome! Could you also take a look at #16996, #17003?

[dstogov]

yeah, they are on my list

Interesting, thanks for explaining the issue and fix!
