This basically means we talk about localization in the respective
localized variant. e.g. "German (Germany)" ➡ "Deutsch (Deutschland)".
If geoip lookup failed or isn't configured for whatever reason it's a
stretch to expect the user to know english enough to find their own
language. Preferring the localized strings resolves this issue.
Additionally this happens to bypass #712 respectively
https://bugreports.qt.io/browse/QTBUG-34287
as the native names are properly spelled. So, as long as Qt has localized
names the names will also be properly spelled.
