[Bug] Eraser Tool not working

[simonbertoli]

Describe the Bug

The Eraser Tool is not working

Steps to Reproduce

1. Install @cornerstonejs/tools^1.70.5
2. Add changes to package outline here [Bug] @cornerstonejs/tools/dist/types/utilities/getViewportForAnnotation.d.ts:2:141 - error TS2307: Cannot find module 'packages/core/dist/types/types' or its corresponding type declarations. #1203 (comment) to avoid build error
3. Add EraserToo, LengthTool and PlanarFreehandROITool
4. Draw a Length Annotation, select the Eraser tool and select the Annotation
5. Error appears in console log, screenshot below is from the Annotation Tools Stack at https://www.cornerstonejs.org/live-examples/stackannotationtools

If we just use the Length tool and do not add the PlanarFreehandROITool, the eraser works as expected. Once both tools have been loaded the error occurs

The current behavior

The annotation is not removed - getting the following error in the console

Uncaught TypeError: interactableAnnotations is not iterable at AnnotationEraserTool._deleteNearbyAnnotations (AnnotationEraserTool.ts:69:32) at AnnotationEraserTool.preMouseDownCallback (AnnotationEraserTool.ts:21:17)

The expected behavior

The annotation is removed and the is no error in the console.log

OS

MacOS 14.4.1

Node version

20.12.1

Browser

Brave 1.65.114

UPDATE

It looks as is const interactableAnnotations = loops through from the PlanarFreehandROITool but returns undefined as the annotation is from the Length tool, therefore causing the 'not iterable' error. If I add a freehand and a length annotation, the eraser tool works as expected.
