When finalizing making a line/multi-poly feature, double-clicking will also zoom in

[BirdSamuel]

To reproduce:

• Start creating a new line/multi-poly feature
• Double-click to finish creating the feature
• While it finishes making the feature, the map also zooms in. It is a little disorienting

@BirdSamuel instead of assuming the index where the interaction control is, we should search for the control to avoid making the code fragile. please fix and test both creation as well as editing exiting geometry.
