This seems to work:

\score {
  \new PianoStaff \with {
    \override StaffGrouper #'staff-staff-spacing #'basic-distance = #20
  } <<
    \new Staff { \clef treble c'4 }
    \new Staff { \clef bass c'4 }
  >>
  \layout { }
}

You can get around this by overriding the script-priority property:

{
  \once \override Script #'script-priority = #0
  \relative c' <e g c>1\fermata^2^3^5
}
