It's not like they are doing it out of intentional malice — they are just "acting naturally". If you play along with it in order to work something out in the short term, expect them to understand that you didn't like it, but let it slide, you'd be gravely disappointed later when they get used to it and start doing it more and more often.
Just like on personal level you have to establish personal space, you have to watch you work relationships to not get out of hand.

Damn, I still ended up giving unsolicited advice 😅, but I think I know what you're talking about and I think this has happened to me more times than I wish it had. True — acting more bold and establishing where you want to be with people early on might make some of them not like you, but in the long run it's a better strategy than getting along with the wrong people, ultimately losing motivation for it and sliding into a "bad state" of sorts.
