Found unstable fingerprints for item_children(cargo_msrv[22a4])

I was unsure whether to submit this issue or not, because I couldn't trigger the same issue (by running cargo +beta run or cargo +nightly run) on the beta or nightly channels. However in the table in https://github.com/rust-lang/rust/issues/84970, I saw for the entry about item_children that it was (supposedly) fixed in 1.54, which is the version I'm running. Sincere apologies if the issue at hand was already addressed.

Code

I did not find a minimal example which triggers the same issue.
