Inactive Qt::Tool window with Qt::FramelessWindowHint flag does not show custom cursor

If the widget is set like this

the_window2 = new QWidget(this);
the_window2->setWindowFlags(Qt::Tool | Qt::FramelessWindowHint | Qt::WindowDoesNotAcceptFocus);
the_window2->setCursor(Qt::OpenHandCursor);

and when the widget is inactive(some other window is activated by the click),
it does not show the custom cursor.

See the video attached.
Actual behavior : QTBUG96374-activate_setcursor.mov

If Qt::FramelessWindowHint is not defined, everything works fine.
See QTBUG96374-activate_setcursor_no_flag.mov

How to reproduce :
1. Use qtbug96374.zip
2. Hover the mouse over the widgets like shown in QTBUG96374-activate_setcursor.mov .

This works fine on Windows.
