Hi, I'm experiencing an issue with the list_pages tool in the latest version (v0.19.0) of chrome-devtools-mcp.

Tool

• list_pages
• Description: Get a list of pages open in the browser.
• Parameters: None

Steps to reproduce

1. Call list_pages to get the initial list of open pages.
2. Close the selected page.
3. Call list_pages again.

Test script used

tests/integration/test_chrome_devtools_mcp_client.py:63

async def test_should_return_list_of_pages_after_closed_selected_page(self):
    """Test that we can call the list_pages tool and get a response."""
    try:
        # first call to ensure the page list is populated
        first_try = await self.mcp_session.call_tool("list_pages", {})
        print("First try result:", first_try.content[0].text)

        # here I close the selected page
        time.sleep(3)

        second_try = await self.mcp_session.call_tool("list_pages", {})
        print("Second try result:", second_try.content[0].text)

    except Exception as e:
        raise e

Output

First try result: ## Pages
1: https://www.google.com/ [selected]
2: https://www.youtube.com/
Second try result: The selected page has been closed. Call list_pages to see open pages.

Expected

After closing the selected page, list_pages should return the updated list of open pages.

Actual

It returns:
The selected page has been closed. Call list_pages to see open pages.
