> Yes. We could use a document property instead like chromium does. Or we could even try to use an isolated world for automation. The other option would be to keep the lifetime of the automation object from C++ like we currently do, but we need a reliable way to release the object when the js context of the frame changes.

We can't use an isolated world, because we are expected to have access to global object properties from scripts.
