As shown in this snippet, the rests are often placed so high that they touch and sometimes also overlap the note beams.

Of course I can lower the rests, but manually doing the thing is tedious.
I would not wonder at all if someone (Rick?) already signaled it.
I was not aware of this. It's just that I encountered it only yesterday.
