Try checking in beta3: https://github.com/godotengine/godot-builds/releases/tag/4.3-beta3

EDIT:
Actually I checked in beta2 and can't reproduce with the attached MRP.

It is probably related to #86661 and should have been fixed in 4.3, so I think it is incorrect to say that it does not work in 4.3.beta2.

I just tested it again after restarting my pc and it works in 4.3.beta2 for me as well.
I'm pretty confident that it did not work otherwise I wouldn't create my first issue here but oh well, it does now.
So I'm sorry if I inconvenienced someone please forgive me <3
