fingering of a grace note overlaps with beam

[Soo Lee]

Hi,

In the example below, the fingering on the grace note B does not show well
because it overlaps with the beam. I do want to keep the stems up and the
fingering up because there will be another voice. What is the best way to
avoid this overlap? Thank you!

\relative c'' {
    g8[ \acciaccatura b-5 a g]
}

Best,
Soo
