#whenCursorPositionChangedDo: can't find slot #cursorPosition

Bug description
SpTextPresenter>>whenCursorPositionChangedDo: should send an event when the cursor position of the text widget changed. However, instead it gets a walkback.

Open text presenter
See walkback. [ SlotNotFound signalForName: aName ] in LayoutClassScope(AbstractLayoutScope)>>resolveSlot: in Block: [ SlotNotFound signalForName: aName ]

connectPresenters

	super connectPresenters.
	self whenCursorPositionChangedDo: [
		Transcript
			cr;
			print: 'cursor position changed';
			flush ]

Expected behavior
An announcement of the changed cursor position would be desirable.
