Description

Use shiny run --launch-browser ... twice (no port argument, so both port 8000). On the second one, even though the port can't be bound, a browser is launched.

Research direction

Reproduce the issue by running shiny run --launch-browser ... twice without a port argument, then trace the shiny run launch-browser handling. Done means the second invocation does not launch a browser when port 8000 cannot be bound, while the first invocation still launches one successfully.
