\RemoveEmptyStaffContext and cross-staff beams

[Jonathan Wilkes]

Hello,
     In the following code, the beam goes between the staves when
\RemoveEmptyStaffContext is commented out but goes above the top 
staff when it's used.
     This means you have to explicitly state all the stem directions to 
get the beam to go in the middle of the staves when using 
\RemoveEmptyStaffContext.

Is this a bug?

Snippet below:

\version "2.13.3"

staffPiano = \new PianoStaff {
        <<
        \new Staff = "rh" { \relative c' {
                c8[ c c c \change Staff = "lh" g, g g g]
                }
        }
        \new Staff = "lh" { \relative c {
                \clef bass
                c1
                }
        }
        >>
}

\score {
        \staffPiano
}

\layout {
        \context {
        \RemoveEmptyStaffContext
        }
}
