`install-browser` command doesn't exist

[uiii]

The help is showing the command exists:

playwright-cli - run playwright mcp commands from terminal

Usage: playwright-cli <command> [args] [options]
Usage: playwright-cli -s=<session> <command> [args] [options]

...

Install:
  install                     initialize workspace
  install-browser             install browser

...

Even

$ PLAYWRIGHT_MCP_BROWSER=firefox playwright-cli open https://example.com
Browser "firefox" is not installed. Run `playwright-cli install-browser firefox` to install

But

$ playwright-cli install-browser firefox
### Browser `default` opened with pid 15038.
- default:
  - browser-type: chromium
  - user-data-dir: <in-memory>
  - headed: false
---
error: too many arguments: expected 0, received 1

It behaves like the install-browser is ignored and runs the open command. I also checked the source code and I haven't found any install-browser command.

Using @playwritght/cli@0.1.1
