StaffGroup starting with grace note

[Ahanu Banerjee]

Hi,

I am having an issue creating a new StaffGroup where one staff begins with a grace note. The key signature for the other staff ends up shifted to the right and collides with the time signature. Please advise how to fix. Thanks!!

\version "2.20.0"
\language "english"
  \new StaffGroup <<
    \new Staff = "Top" {
      \key ef \major
        g'1
    }
     \new Staff = "Bottom" {
       \clef bass
       \key ef \major
       \acciaccatura <c, g,>8
       g1 |
    }
  >>
