You are saying that this problem doesn't exist on master?  If so,
perhaps we should consider backporting some of the changes on master
to emacs-30 (if that's feasible)?

I think it's the correct direction, but wouldn't it be easier to make
this a frame parameter instead?  Then the defcustom could be nil by
default, and if it's non-nil, it would override the frame parameter.
The bonus will be that users will be able to define different styles
even for frames of the same type.  Another bonus is that the
frame-parameter machinery is well-tested, so the change will be a
low-risk one.

WDYT?
