Windows Tablet Laptop with "flipped" primary and secondary button also flips the buttons on the stylus.

When using a certain brand of tablet laptop and switching the mousebuttons (i.e., left becomes right mouse button and right becomes left mouse button). The stylus will send mouse events for the right mouse button instead of the left mouse button. This only happens in Qt applications that are using standard mouse functionality (e.g., pointing and clicking), not with other Windows applications.
