QPicture doesn't respect Qt::IntersectClip when used with setClipPath

When I define a clipPath in a QPicture with Qt::IntersectClip, it overrides the clipPath or clipRect defined in the QPainter which draws that QPicture.

It works fine when I define a clipRect in the QPicture, thanks, I presume, to this fix https://codereview.qt-project.org/c/qt/qtbase/+/104908

I think that the same fix should be done for the setClipPath method.

The attached example illustrate that (click on the button to switch between the cliprect and clippath)
