--wait doesn't appear to work quite right?

[colemickens]

I'm running this command from a terminal inside OpenVSCode-Server:

jj \
  --config-toml='ui.merge-editor="openvscode-server"' \
  --config-toml='merge-tools.openvscode-server.merge-args=["--wait", "--merge", "$left", "$right", "$base", "$output"]' \
  resolve

While I'm able to do the merge as I might expect, saving and closing the file does not return / complete the --wait.

Is there something else I can do here to successfully use OpenVSCode-Server as my merge tool?
