Custom percussion style is ignored for the first note when it is a grace note

There seems to have been various reports of bugs when the first note is 
a grace note, but this bug has been in many LilyPond versions to date.

When the first note of a drum score has a grace note, LilyPond outputs 
the default note, rather than the custom percussion style.

In this case, \acciaccatura is used to create each grace note - main 
note combination.

Here's a "Tiny example":

\version "2.24.0"
#(define mydrums '( (hightom default #f 3)))
\score {
   \new DrumStaff <<
     \set DrumStaff.drumStyleTable = #(alist->hash-table mydrums)
     \new DrumVoice { \voiceTwo \drummode { \partial 2 \acciaccatura 
tomh8 tomh4 \acciaccatura tomh8 tomh4 } }
   >>
}

The first combination outputs the default tomh for the first grace note, 
with the main note output from the custom mydrums.

The second combination produces the expected output.

Here's a workaround (full bar instead of partial, which is not what was 
required):

\version "2.24.0"
#(define mydrums '( (hightom default #f 3)))
\score {
   \new DrumStaff <<
     \set DrumStaff.drumStyleTable = #(alist->hash-table mydrums)
     \new DrumVoice { \voiceTwo \drummode { r2 \acciaccatura tomh8 tomh4 
\acciaccatura tomh8 tomh4 } }
   >>
}
