Context

I'm using an API that returns a gzipped response, but the reported Content-Encoding is x-gzip rather than gzip, so urllib3 fails to decompress it.

According to RFC 9110:

A recipient SHOULD consider "x-gzip" to be equivalent to "gzip".

Therefore, I would expect e.g. Response.read(decode_content=True) to automatically decompress such responses.

Unfortunately, I can't find a public server that would produce such responses, so I can't provide a simple reproducer.

Alternatives

I can set decode_content=False and gunzip the content manually.
