If Graphics view is nested few mouse input does not work.
In attached example nested graphics view does not show mouse cursor or context menu on one of the line edit but other one works.
The "line edit1" works as expected, i.e. if I give it the focus, I see a blinking cursor and the context menu opens when using right mouse button.
The "line edit2" (the "nested" one) does not work as expected, i.e. it does not show a cursor and also the context menu does not open (anyhow the line edit is still editable).
Our Document says Nesting is supported.
