    Description

      When using a touchpad, on linux and MacOS X, you can scroll horizontally, vertically or in any direction with two fingers.

      In QWebEngineView, the wheel event (when not using the passive mode), triggers many events with deltaX and deltaY both equal to zero when the scroll is not perfectly horizontal or vertical.

      It seems like the first wheel event is correct, while the next ones are wrong.

      Attached is a minimal pyside6 + QWebEngineView + javascript example to reproduce the bug and display the deltaX and deltaY.
