help request header cookie

Description of the bug

I'm using the get_network_request method from chrome_dev_tool_mcp, but the Cookie header is missing in the request headers.
However, when I inspect the same request directly in Chrome DevTools in the browser, I can clearly see the Cookie header in the request headers.

this is chrome dev_tool

this is chrome dev_tool mcp

The MCP server requires the current Stable Chrome version (the version mentioned in the description is Chrome/135.0.7049.78). Can you reproduce it with the latest version?

chrome 142.0.7444.60

chrome browse :

chrome_dev_tool_mcp :

Many fields are missing from the request headers — please help explain the possible reasons.

[OrKoN]

The reason is probably Puppeteer not seeing the headers set by the network stack in Chrome and only sees headers from before the network stack.

@Lightning00Blade could you please check?
