I think this for loop with the awaited promise will be blocking -- would it be better to map these and use Promise.all to ensure each completes if we do need to wait on these?

It's intended to be blocking and will await all of them as-is. Using Promise.all would run them in parallel, but I'm not sure that's advisable with CDP. I think it's a safer bet to run them serially.

Why wouldn't that be advisable with CDP? I think using Promise.all makes sense here as well.

I thought there was a case where CDP had trouble with too many commands being run at once, but I can't find that instance. I updated it to run the target closing in parallel.

Additional details
Closes any extra targets (tabs/windows) between tests so that new tests always start with only the main Cypress tab, in order to maintain test isolation and a clean slate before each test. This is in anticipation of support for testing multiple tabs/windows with the future
