--- Comment #5 from A Wine user RandomAccountName@mail.com --- This seems to work in wine-1.9.6-66-g329dfee.
The current winetricks recipe adds a native override for wininet, so I tested with the override removed, and again with a builtin-only override for wininet. InPrivate Browsing works in both cases.
