Gracenote accidental placement in strict-note-spacing

[Knute Snortum]

I have come across what may be a bug.

Below is a tinyish example of gracenotes with strict-note-spacing.
The problem is the fis accidental.  There's not enough space for it.
(See attached picture.)

%%%
\version "2.23.6"

rightHand = \relative {
  \override Score.SpacingSpanner.strict-note-spacing = ##t
  \newSpacingSection
  g''4 \grace { a8 g fis g } a4 f
}

leftHand = \relative {
  \clef bass
  g16 16 16 16 fis16 16 16 16 f16 16 16 16
}

\score {
  \new PianoStaff <<
    \new Staff \rightHand
    \new Staff \leftHand
  >>
}
%%%

Is it a bug?  A known problem?  (I did search issues and found
nothing.)  Maybe I'm doing something incorrectly.
