\partCombine \acciaccatura slashes other flags

The slash from the acciaccatura gets deported on all subsequent 8th flags.

Is this a known bug ?

\version "2.25.10"

\partCombine
{\acciaccatura {c''16 b'16} a'1| g'8 r r4 8 r8 8 8 | 8}
{\acciaccatura {f'16 g'} a'1 | e'8 r r4 8 r8 8 8 | 8}

Took me quite a while to figure what was going on here as the \acciaccatura
is about 20 bars before the glitch and only in the partCombined part to
which this bug is obviously related. Added to my \partCombine caveat list
:-)
