Follows commit: ffef01e327.
It caused an issue in Firefox:
On the sale order form view (with the field "notes" handled by the OdooEditor),
clicking on a Many2one made the browser crash because the method getSelection
did not exist on the target which was the input element.
It did not crash in chrome as the event's target was always the Document.
The added test actually tests the feature of the referenced commit, and checks, as much
as possible, that there is no crash.
