Description

Right now when using ModifyMode with lockRectangles: true it is possible to click on a corner of a rectangle and remove that corner.

Expected Behavior

Since rectangle should be "locked" it should not be possible to remove its corner, since it makes this shape to no longer be a rectangle

Steps to Reproduce

1. Create editable layer. Make sure to enable lockRectangles: true in modeConfig
2. Draw a rectangle
3. Click corner of the rectangle

Environment

• Framework version: deck.gl@9.1.12, deck.gl-community/editable-layers: 9.1.0-beta.5
• Browser: 139.0.1
• OS: Linux
