[andreubotella]

See #12771 and #12814.

Needed to reland #12908, which was reverted in #12929.

@bartlomieju @bnoordhuis PTAL. Reviewing with "hide whitespace" turned on helps.

Restarted the CI because the test failure looks like a flake. Preserved here for posterity:

Closed and reopened because the license check was stuck in yellow.

Oh no, I added that test 😓

EDIT: maybe you just got lucky and the randomly generated IV was actually the correct IV? If so... wow. You literally win the lottery today. Otherwise - no idea what is up with that.

LGTM too
