Beam on wrong staff (2.11.25)

In the first two measures of the following excerpt the beam ends up on the wrong
staff. 

- When I take the slurs out it looks fine.
- It seems that the problem is the staff change that follows. This line by
itself causes the problem: \change Staff=LH aes8( aes aes aes aes aes) | \change
Staff=RH
- A workaround is to do each section with the staff change in its own voice.

Thanks!
