Is nullOut (or rather !nullOut) serving the same purpose as isOrphanedBrowserProcess?
There was a problem hiding this comment.
I don't think so. I think the goal of nullOut is to set the current browser instance to null, which we don't want to do since we want the active instance to be set, but the _instance inside the closure to be cleaned up.

Additional details
This PR fixes an issue where orphaned processes were killing the whole electron browser CRI client, when in actually we want to preserve this until the electron process is terminated.
Unique to our electron setup, launching electron produces a window and not a separate browser instance. Since orphaned processes (or in this case, windows/targets) need to be cleaned up, we want to only clean up those items related to the process/window and not the overall launched instance.
see #28397 (comment) for more in depth details, as well as how we reproduced the issue
