Use the existing background context instead of creating a new one.
Use the existing background context instead of creating a new one.
Since the context that is used is a essentially a background context, we need to have a timeout in place. There is a chance that the browser process has already exited but the connection thinks it is still alive. By using the timeout we're ensuring that the iteration can end, which allows for the events to be emitted by the k6 event system and so allow k6 to exit in a timely manner.
Working with c.ctx will essentially never end since it is basically a background context. Using the passed in context which has a timeout will help ensure the send goroutine ends quickly.
The PR we're interested in is grafana/k6#3968.

What?
We're putting a timeout on the CDP close request.
Why?
This is so that the connection is closed and we allow the iteration to end. Without this, the browser module can be left hanging indefinitely on the cdp send (well, waiting for the response from chromium) when actually chromium has already exited.
