I haven’t looked through the other drawing tools, but any draggable component will be broken if it defines its own custom pointer event handlers. The fix, in #6550, is to ensure that any existing handler is always called, for each pointer event. Otherwise, adding a custom handler to a draggable component can prevent the corresponding draggable handler from running.

In this case, polygon tools add a pointerdown handler which overrides the draggable pointerdown handler.
