unable to interact with browser with multi-turn chating - using Playwright MCP

[rax02]

Building an agent to navigate and do task using browser.
There is only root agent with Playwrite-MCP tool. using adk-web to interact with agent.

Issue: When giving second instruction, the current session of browser get closed and new session starts. And the last session snapshot get lost.

How to keep the browser session active, so that it can follow the instruction one after another? Does adk create new connection every time with the mcp server?

    instruction='''
    You are a snapshot-mode intelligent web automation agent.
