The overflow only happens if alloc is compiled with overflow checks enabled and the passed capacity is greater or equal 2^(usize::BITS-1). The overflow shadows the expected "capacity overflow" panic leading to a test failure if overflow checks are enabled for std in the CI.
Unblocks CI: Enable overflow checks for test (non-dist) builds #89776.
For some reason the overflow is only observable with optimization turned off, but that is a separate issue.
