QNetworkReply: it is confusing whether the reply data has been decompressed or not.

If the header 'Accept-Encoding' is manually set, QT will not decompress the reply data before https://github.com/qt/qtbase/commit/6f25051536c1636688a0a0939196007aac34676d.

However, now if the zerocopy buffer is not used, the reply data will be decompressed (example link1). Otherwise, the reply data will not be decompressed (example link2).

Relevant code:
