[Bug] `--save-video` does not work with `--extension`.

[AndrewSouthpaw]

Current version: v0.0.40.

If I use this MCP configuration, video capture does not work:

"mcpServers": {
  "playwright": {
    "type": "stdio",
    "command": "npx",
    "args": [
      "@playwright/mcp@latest",
      "--extension",
      "--caps=tracing",
      "--save-video=800x600"
    ],
    "env": {}
  }
},

I need to remove --extension for the system to correctly save videos. Is that expected?

I also saw #1084, I'm not sure if that's related, but it seems different.

That's correct. We can however introduce a capability that starts and stops the video for extension too. Leaving this open.

We now have devtools capability that starts and stops the video.
