Problem with dragging points and updating lines in the newest version of the annotation plugin

Hi!
I'm a developer working on GetODK in our mobile app we use Mapbox and the annotation plugin which we wanted to update to the newest version 9:0.9.0 but we discovered regression.
In our app we allow selecting points on a map and we draw lines between them (it's geo shape or geo trace). We also allow dragging those points and redrawing those lines while dragging so that everything is smooth:

The problem is that after updating to 9:0.9.0. The dragging process is terminated immediately after starting when we update lines (calling AnnotationManager.update(T annotation).

The implementation is here https://github.com/getodk/collect/blob/master/collect_app/src/main/java/org/odk/collect/android/geo/MapboxMapFragment.java#L914
we override onAnnotationDrag to update points and lines.

The problem seems to be in updating lines because when we call
AnnotationManager.update(T annotation) -> updateSource() -> draggableAnnotationController.onSourceUpdated() -> stopDragging(draggedAnnotation) and as result our dragging process is immediately stoped.

It wasn't the case in v9:0.8.0. Could someone explain why this behavior changed and why when we want to update lines the dragging process is terminated?

Bắt đầu tại collect_app/src/main/java/org/odk/collect/android/geo/MapboxMapFragment.java, khoảng dòng 914, nơi onAnnotationDrag cập nhật các điểm và đường. Theo dõi AnnotationManager.update qua updateSource và draggableAnnotationController.onSourceUpdated, sau đó so sánh hành vi giữa các phiên bản plugin 9:0.8.0 và 9:0.9.0. Hoàn thành khi việc cập nhật các đường không còn lập tức kết thúc thao tác kéo điểm.
