Note: mainFrame can be null. It is null when the WebPageProxy is first created. I am not sure on when it is available yet, be we should null check it.

We will likely need these messages to the UIProcess to implement execute_async or any other events.

Just a test. This would call JSEvaluateScript and pass the result to the injected script for processing (turning elements into handles, etc.)

This gets called in the end by requesting the refresh endpoint right now.

Needed so we unprotect our script object ref.
