when I first read this PR, I was concerned that this change to this test does not represent a pure revert of the change in behavior injected by #96862 (see specifically https://github.com/rust-lang/rust/pull/96862/files#diff-7e1f76bb00c9a4c88616e00451baa4b95f56d066d893b0bd781f17dadfcf1338 , which changed a different line in this test).

However, @nbdd0121 has pointed out to me that we never intended to specify how drop interacts with casting of C enums, and in fact #97652 made the pre-existing lint against such casts into a future-incompat error. So I am no longer concerned about the change in behavior to this test.
