MS3β voice-changing buttons lose visible truncation of note

Exploring new buttons in the new piano roll editor, I discovered the "1 2 3 4" at top that moves any selected note between sub-staff voices, as well as the itty-bitty numbers in the note graphics that identify the voice! Wow!

It turns out that if you change the length of the note, which you see immediately in the shortening of the graphic, that visible shortening is lost if you indeed click one of "1 2 3 4" to change the sub-voice, although the "length" box continues to show the new value.
