What is "your setting", and how is it not honored by Emacs 29?  Please
tell the details, preferably in the form of a reproducible recipe
starting from "emacs -Q", so that we could investigate and try to fix
what became broken.

As a matter of fact, we are trying very hard not to break past
behavior, and when that is for some reason unavoidable (and I'm not
saying this is the case here), provide options to get back the old
behavior.  Occasionally, we make mistakes and fail to do TRT, but
there's definitely no intentional breakage of past behavior.  Quite
the contrary.

So please bear with us and help us repair what we inadvertently broke.

TIA
