blacksun a69e39cd2f Fix crash: In Xref link widget, If there is an element being added (element pose mode), and this one is compatible with the type of Xref sought by the widget, then the widget show this element. ...

When user finish the element pose mode, the element under the cursor is deleted, but continue to be show by the widget.
So, click on this element in the widget cause a crash.
This case come when user add element and go to another diagram without finish the pose mode, and open Xref link widget from an element in this other diagram.
