Actually, I think I would get the same result as you in this case if I
had sh pointing to bash.

dash -c xpdf produces

xterm
`-zsh
  `-dash
    `-xpdf

but bash -c xpdf produces

xterm
`-zsh
  `-xpdf


That's why I said I thought bash performed a kind of optimization to
reduce the number of processes while dash (default for sh on Debian and
Ubuntu nowadays) did not. As I think, notion uses the system command to
launch external apps, and system calls sh -c, I get a lot of unecessary
processes.
