Title:
  [systemd-coredump] ProcessSizeMax setting does not seem to have any
  effect

Status in systemd package in Ubuntu:
  Expired

Bug description:
  The systemd-coredump ProcessSizeMax setting does not seem to have any
  effect. Steps to reproduce:

  ```
  sudo apt install chaos-marmosets systemd-coredump
  sudo mkdir /etc/systemd/coredump.conf.d/
  printf "[Coredump]\nProcessSizeMax=10K\n" | sudo tee /etc/systemd/coredump.conf.d/limit.conf
  divide-by-zero
  ```

  Running `coredumpctl` shows that the dump was written in full size,
  but the ProcessSizeMax should have caused the dump to be truncated.

  ```
