\oneVoice bug (was "staccato oddity")

Hello, all --

Turns out \oneVoice (the pre-defined property) looks like this in 
property-init.ly:

% dynamic ly:dir?  text script, articulation script ly:dir?     
oneVoice = #(context-spec-music (make-voice-props-revert) 'Voice)

Does that mean that dynamic and text/articulation script are not 
handled (as would seem to be the case)? Is this a bug?

Thanks,
Kieren.

p.s. for what it's worth, the current workaround is to use \oneVoice 
\scriptBoth where you are "reverting"
