Inconsistent labeling & style behavior of articulations (esp. "Muted (closed)")

The + symbol, Muted (closed), can be found in the Articulations palette, and is labeled an "Articulation" in the infobar below the score, as expected.
However, in the Inspector it has a section titled Ornament, where others - e.g. ○ (Open) - have Articulation.

Even more confusingly (perhaps warranting a separate issue, but it seems related):
For both mentioned, as well as many others from the Articulations palette, the style default for properties like Anchor is in fact linked to that of ornaments (Mordent, Trill, Turn, ...), not articulations (Accent, Marcato, ...).

(See Imgur for a version without the ghastly dithering. Can't upload webm here. EDIT: fixed it in the gif.)
