Context:

• Playwright Version: 1.32.1
• Operating System: macos
• Python version: [e.g. 3.7, 3.9]
• Browser: all

Describe the bug

I'm running a gRPC server using a loop, and then using playwright to fetch some URL: https://github.com/hwchase17/langchain/blob/e3b7a20454cea592fc6d0a0d91c36206e8ad6790/langchain/document_loaders/url_playwright.py#L62

when the context is exiting, this error is thrown
RuntimeError: Set changed size during iteration

this is happening due to an old upstream bug in cpython python/cpython#80788

we need to refactor the context manager to close itself differently

TBH, I don't know why we even do that :O
