Running chisel server in a docker container does not seem to re-read the authfile

When chisel is started in a container, it reads the authfile on startup, but does not seem to notice when the file is modified if it is mounted using a -v option:

#!/bin/bash


export CHISEL_LE_EMAIL=some@email.addr
docker run --net=host --name chisel --restart always \
  --log-opt max-size=10m --log-opt max-file=2 \
  -d -e PORT=443 -v /home/MYUSER/chisel:/chisel jpillora/chisel server \
  --authfile /chisel/users.json \
  --backend https://some.other.server \
  --reverse --tls-domain this.server --pid -v

This works really well as a chisel server, and restarts on server restart etc. However, if the users.json file in /home/MYUSER/chisel/users.json is updated, the server does not notice and re-read the file.

Is there some further configuration that is needed?

Start with the chisel server entry point and the mounted /chisel/users.json authfile described in the report. Reproduce the Docker bind-mount setup, update users.json while the server runs, and determine whether the server reloads it; done means updated authentication takes effect or the required configuration is documented.
