fix(nodes): hide the editor's native widgets through one helper (#90)

The Save to library switch copied the text fallbacks' zero-height computeSize
arrow, and neither copy was ever called, so focused-node.js function coverage
fell to 87.5 (floor 90). One hideNativeWidget helper now hides both, and the
spec checks that the hidden switch and a text fallback take no node height.
