"Get" returning error on non 2xx response

[N0ct3]

Hello,
This might actually be more of a question than an actual issue:
The http.Client.Get doc states that:

An error is returned if the Client's CheckRedirect function fails or if there was an HTTP protocol error. A non-2xx response doesn't cause an error.

My understanding is that a retryablehttp.Client with default configuration would behaves similarly, retrying up to 4 times, and returning the response, no matter what the status code is, as long as there is no error.

But it seems that if the client doesn't get a success status in the configured number of retries, it WILL return an error similar to Get ...: GET ... giving up after 5 attempt(s), instead of returning the response with the non success status code.

Am I misunderstanding the doc?

Anyway, setting the client's ErrorHandler to retryablehttp.PassthroughErrorHandler seems to give what I expected to be the default behavior.
