CK II - Can't rename descendents on unions where player is inferior side (3.0.0.0)

[Stupidity]

One line summary of your issue
Can't rename descendents on unions where player is inferior side (3.0.0.0)

Game Version
3.0.0.0

What expansions do you have installed?
All of the above

Do you have mods enabled?
No

Please explain your issue is in as much detail as possible.
I have Customization pack and it says in the description "Rename children born to all your descendants (not just your own children)" but I can't even rename my own children when my male character is in a matrilineal marriage. I used to be able to name them back in 2.8.x

Steps to reproduce the issue.
1. Start as a man of concubinage religion (for women without religion mods it would be difficult to avoid game over in 1 generation)
2. take 1 concubine and get matrilineally married
3. get them pregnant (console command or seduction)
4. wait till childbirth

Expected result: I should be able to name both children
Actual result: I only can name my kids in my own dynasty

Yes, I guess the description is a bit lacking - they don't mean descendants, they mean dynastic descendants. It also makes sense because you should have no say in what another dynasty names their children. If you agreed to let the other dynasty dominate the marriage and for the kids to belong to them, you should not have the power to name them "Retard the 1st" until you're surrounded by enemy rulers with silly names (except in modded games).

By the way, when the AI chooses names for their children, it also tends to often choose names of previous dynasts (e.g. grandfather's name), so that your names proliferate and become traditional dynastic names very soon. So the ability to choose a name for all children of your dynasty under 12 is already very powerful.

I used to be able to name my children regardless which dynasty they belong to back in 2.8... Perhaps make an exception for Player's chldren because... Customization kit?
