// In all tests, headers added to requests are copied on the heap using strings.Clone.
// This was originally a workaround for https://github.com/golang/go/issues/65286#issuecomment-1920087884 (fixed in Go 1.22),
// but this allows to catch panics occurring in real life but not when the string is in the internal binary memory.
