Process stuck due to potential unhandled TargetClosedError

[jasondoc3]

Step To Reproduce / Observed behavior

It has been challenging to reproduce the issue since the connection is established via CDP to a remote Chromium browser. However, over the past day, I have intermittently encountered an unhandled TargetClosedError. This error causes the Ruby process running the Playwright Ruby client to consume a significant amount of CPU and hang indefinitely. Here's some of the output when running the process with DEBUG=1. It appears the page is never successfully opened.
