The Extract row's vocal mode buttons read as stems rather than as a setting on Vocals #669

What goes wrong

The Extract row reads: All, Vocals, All, Lead + Backing, Drums, Bass, Guitar, Piano, Other.

Four of those are stems and two are a setting on one of them, and nothing on screen says which is which. "All" and "Lead + Backing" sit as loose chips among the stems, so they read as peers of Drums and Bass rather than as a choice about the chip immediately before them.

It is also half of why the two controls called "All" are confusing (#659): the second one is not obviously attached to anything.

What it should do

Show that the two mode buttons belong to Vocals, without making the row taller or the chips a different size from each other.

Constraints for whoever fixes it

• Every chip in that row is 30px. A wrapper with its own padding and border makes the group 38px and it hangs below everything beside it, which is worse than the problem.
• The mode buttons are only on screen while Vocals is selected, so whatever marks the grouping has to survive them appearing and disappearing.
• Colour is already carrying state in that row: a selected stem is tinted, and the active mode is tinted. Anything that tints the group as a whole makes the inactive mode look selected.
