When clicking and dragging on a DISABLED QGraphicsView component on a QMainiWndow, the whole application is moved. This happens with the component at ANY level, from central widget down to any level (this works even on complex UI hierarchies, doesn't matter if containers are enabled or disabled).
Attached are 4 files for demonstrating the issue.
The expected behayiour would be the events (clicking + dragging) to be ignored as it happens with ANY other disabled component (buttons, anything else)
Instead, the WHOLE application moves.
