Looks like my new api test is failing in the bot. The bot has CFPREFS_DIRECT_MODE disabled, which is a configuration I cannot test easily. I will try and figure it out. @Per: please let me know if the issue is obvious to you since you are more familiar with this code.

Does TestWebKitAPI need to be brought into the foreground for the preference change to be picked up, since the preference observer in the UI process is started when the UI process becomes foreground?

Yes, it does. See my earlier comment.
