I have been running into... not quite a bug, but an "ugly" (bugly?) where the accent is engraved too close to a note with an acciaccatura and a slur. Here's a MWE:
%%%
\version "2.25.18"
\fixed c' { \acciaccatura { f8 } e4->^( f4) }
%%%
At the moment I just adjust the accent's Y-offset, but is there a better way to deal with this? Should I create a bug report for this?
