Duplicate Stellaris - Federations immediately collapse after formation [v3.4.3] [d7c6]

Description
Federations immediately collapse after formation [v3.4.3] [d7c6]

Game Version
3.4.3

What version do you use?
Steam

What expansions do you have installed?


Do you have mods enabled?
Yes

Please explain your issue is in as much detail as possible.
In short, federations will collapse immediately after formation, if the player (or AI) has a subject which the other AI does not like.

So for example:
1. Empire X (player or AI) demands subjugation of empire Z (which I have noticed is usually a former part of empire Y, separated due to rebellion etc.) => empire Z becomes subject of empire X.
2. Empire X or Empire Y ask to form a federation with each other, with high acceptance.
3. The federation is formed, and a few days later it will immediately collapse due to the participation of empire Z inside the federation, which empire Y does not like.
4. The federation remains in existence even if only empire X and Z are the only members left.

(Not sure if this is a bug or (un)intended feature, but even so, I believe it should be the case that then empire Y should have very low acceptance to join the federation, or there should be some other solution. )

Steps to reproduce the issue.
See above. The mods I have installed do not directly nor indirectly affect the aforementioned game systems (the mods make UI changes and add colors), and the issue persists without mods.

I attach 2 separate save files (they load without mods) where this has occurred (before save date), I give the details here:

autosave_2369.01.01.sav:
- Harmonic Oscillator (AI) and Garlean Empire (AI) tried to form a federation which split apart almost instantly, due to presence of Consolidated Stalker Provinces (subject to Garlean Empire, but former part/subject of Harmonic Oscillator)

autosave_2298.01.01.sav:
- Shell plc (Player) and Salorim Pact (AI) tried to form a federation together which split apart almost instantly, due to presence of Chimera Ant Prime (subject to Shell plc, but former part/subject of Salorim pact)
- I 'fixed' this by releasing Chimera Ant Prime as a subject and then forming the federation again (as seen in the current year of the save).

so is this a new bug due to changes to vassals?

I've got no idea if it was possible, but I never encountered this before Overlord. I never really vassalized people before the changes, so it might just be that I never noticed it.
