I cannot reproduce this in Emacs 30: with the above recipe I get the
same scroll-bar-width as the value I set before quitting the session.
So please verify that Emacs restores the desktop from the correct file
(it could be modified via desktop-path), and if it does, then perhaps
this is specific to your Emacs configuration and/or the toolkit you
are using, or perhaps to some of your customizations.  I've reviewed
the code in frameset.el, and I don't see there anything that would
explain why scroll-bar-width frame-parameter would not be applied when
restoring the desktop.
