Corresponds to the newly created context for display purposes. The origin should be formatted like a URL, but with only the scheme, host, and port (if necessary), like the value of the url.origin property of a URL object. Most notably, this string should omit the trailing slash, as that denotes a path.

If set to afterEvaluate, microtasks will be run immediately after the script has run.
