With quite some effort I achieved more or less what I was trying to copy in the first two bars. The main point being to get the grace notes to sound before the bar line.
Trying to use Melismatic (3rd and 4th bars) is not an obvious success, not least because it only extends for the length of the rest in the rest chord.
You might try putting a header and footer on that clip.
The problem is not the RestChord. It is the Rest(s). Melismatic does not seem to allow them.
