Keeping Qt 5’s current behavior makes it impossible for an app to distinguish between multiple presses and a double-click without duplicating the timers in QApplication. Applications that rely on the original behavior are likely to be confused by the state you enter when receiving the second press.

http://qt-project.org/doc/qt-5.0/qtwidgets/qapplication.html#doubleClickInterval-prop

Sending the press event before the double click looks like a mistake, I wonder if it’s the same on all platforms. I would be surprised, as it would break all apps that handle more than simple mouse events. A git bisect is probably a good idea...
