"Move Program Counter Here" command not available when debugging script in a docker container
I'm debugging various scripts running in a docker container. I can debug them fine following the instructions in here https://wingware.com/doc/howtos/docker However, the "Move Program Counter Here" command, which I often use, is greyed when I debug scripts running in a docker container. The command it's available when debugging a script in the host. I've tried to call the command directly from the "Command by name" option and typing debug-move-counter or debug-move-counter-clicked, which works well when debugging a script in the host, but I get the message Command not found.
I've run the "Reload all scripts" option but it the debug-move-counter is still not available.
How can I make this command available when debugging a script inside a docker container?
