runtime: HttpClient deflate decompression error

Hi, I just tried to move project from Net 5 to latest preview of Net 6 and I have noticed issue with automatic decompression. Gzip and Brotli seems to work fine, but Deflate is throwing IO error with invalid stream data. When I change back to Net 5, everything works fine again. Here is part of code that throws the error on last line with stream.ReadAsync. I think this happen only when the website is using https and I receive response compressed with Deflate, also the HttpCompletionOption.ResponseHeadersRead might be causing some issue.

var _httpClientHandler = new SocketsHttpHandler
{
    AutomaticDecompression = DecompressionMethods.All
};
var _client = new HttpClient(_httpClientHandler, false);	
var response = await _client.SendAsync(request, HttpCompletionOption.ResponseHeadersRead,)
if (response.IsSuccessStatusCode)
{
    Stream contentStream = await response.Content.ReadAsStreamAsync(_token);
    if (contentStream != Stream.Null)
    {
        int readBytes = 0;
        var rentedBuffer = pool.Rent(64 * 1024);
        var bufferMemory = new Memory<byte>(rentedBuffer, 0, rentedBuffer.Length);
        int readChunk = await stream.ReadAsync(bufferMemory.Slice(readBytes));
    }
}

System.IO.InvalidDataException: The archive entry was compressed using an unsupported compression method.
