removePointModifier with CesiumEventModifier.SHIFT not working for Polylines and Polygon Editor

[qandeelabbassi]

Changing the value of removePointModifier to CesiumEventModifier.SHIFT has no effect on PolylinesEditorService or PolygonsEditorService. The default option (simple right-click) still remains active.
But if I change the modifier to say CesiumEventModifier.ALT, then the modifier works as expected

Intended outcome:
The point should only be deleted when right-click action is performed with the SHIFT key

Actual outcome:
The point is deleted only when simple right-click action is performed. It doesn't work with the SHIFT key

How to reproduce the issue:
Change the removePointModifier to CesiumEventModifier.SHIFT and then after creating a new polygon/polyline try deleting a point with right-click+shift key
