FYI @DanTup, this looks like the same failure as in https://github.com/dart-lang/sdk/issues/56965.

Yeah, this is the same. Still trying to get to the bottom of it. I repro'd it locally and fixed, but it turned out I must've repro'd it in a different way to what was happening on the bots because the bot still failed.
