You probably want

\score {
  \new ChoirStaff  \with { \accepts "TabStaff" }
  <<
   \new Staff \mus
   \new TabStaff \tab
   >>
}

The point of a ChoirStaff is, uh, to have bars not going through
vertically but still get a bracket.

Well, uhm.  Sounds like accepting TabStaff by default might be sensible
to do?

At any rate, what happens here is that the ChoirStaff creates a
StaffGroup in order to contain the TabStaff, and you see the bracket of
the implicitly created StaffGroup.
