Codex having issues with BrowserMCP

I used BrowserMCP with Claude Code and had no issues at all, but I've recently switched to OpenAI's Codex, and while it can see the MCP, it insists that it can't see the tab i'm connected to, only an about:blank page. It's acting like a headless browser, rather than seeing my already logged in connected tab, which is the main reason why i find BrowserMCP so useful.
