In Dash, users need to know when the viewer has cleared the selection box by double clicking outside of it. Right now, single-clicking outside of the selection box doesn't clear the selection box but it emits a selected event with no data. Double-clicking outside of the selection box clears the selection box but it emits the same selected event with no data. There is no way to distinguish between these two actions right now.

Ok. I'll close this.

Perhaps we should revisit how plotly_selected is triggered when no points are selected in v2? (see #168 for more). Maybe it shouldn't be triggered at all?
