Add a regression test for #132587

[jieyouxu]

#132587 partially reverted #129346 because that caused a test failure in cfg_eval, but the revert PR didn't come with a test because it involved proc-macros and was hard to minimize. We should still add a regression test.

I briefly looked at this and the minimization is tricky.
