Console output: [mobx-state-tree] You are trying to read or write to an object that is no longer part of a state tree. (Object type: 'BrushRegionModel', Path upon death: '/annotationStore/root/children/0/drawingRegion', Subpath: 'maskDataURL', Action: '/annotationStore/root/children/0/drawingRegion.commitDrawingRegion()'). Either detach nodes first, or don't use objects after removing/replacing them in the tree.
