* test: reproduce #267 (timeline.delete of a sketch leaves later features that use its body by name) * fix: timeline.delete reports features that newly fail (#267) A later feature that names a deleted body (a combine targeting a deleted extrude's body) is listed under failing: [{feature, error}] in the reply instead of failing silently.
