bug#74409: 30.0.92; customize buffer for bibtex-biblatex-entry-alist also shows unformatted variable value

[Roland Winkler]

In emacs -Q load BibTeX mode and run

M-x customize-variable RET
bibtex-biblatex-entry-alist RET

The top of the customize buffer is clogged with the unformatted
variable value that hides the actual customization buffer.

I do not know whether this is related to bug #53606.  Like bug #53606,
the problem did not exist in earlier version of emacs (say, emacs 26.3).
But it started some time ago (confirmed with emacs 28.2).
Nothing changed on the side of BibTeX mode back then.

 3.24.38, cairo version 1.16.0) of 2024-11-01 built on regnitz

It looks like the value of the variable was not shown in Emacs 26, but
is shown now.  Bisecting to find the offending commit would be highly
appreciated.

Thanks.
