Hidden location pushed to ActivityPub

[lostfocus]

Not sure if the real culprit is this plugin or https://github.com/Automattic/wordpress-activitypub (maybe @pfefferle has an idea?) - I always have my post location hidden and with my last post (https://lostfocus.de/2025/02/05/tapestry/) the info got pushed out to ActivityPub as well:

Any idea what might have happened? Interestingly enough the first version that got pushed didn't have the location and when I updated the post (because I missed a word) the hidden location got tacked on. I deleted the location from the post and saved it again, now it's not visible anymore.
