Vertical positioning of temporary staves

[Phil Holmes]

Using the code below, I get the temporary staves vertically offset, as shown
in the attached image. It appears that they are avoiding each others'
non-existent horizontal extent. Is there any was of lining them up
vertically?

\new Staff = "Permanent"
\relative c'' {
c c c c
<<
{
c c c c
}
\new Staff \with {
\remove "Time_signature_engraver"
alignAboveContext = #"Permanent"
\override StaffSymbol #'staff-space = #(magstep -3)
fontSize = #-2
}
{
c c c c
}
>>
c c c c
<<
{
c c c c
}
\new Staff \with {
\remove "Time_signature_engraver"
alignAboveContext = #"Permanent"
\override StaffSymbol #'staff-space = #(magstep -3)
fontSize = #-2
}
{
c c c c
}
>>
c c c c
}
