I noticed after updating texlive about a week or so ago, I started seeing
domfilter error which were not there before.
After some debugging, it turns out they come when adding
\begin{thebibliography}{1}.
Here is a MWE. Using TL 2025, updated today. This file compiles with no errors
in lualatex

lualatex index.tex gives no warnings and no errors.
Do I need to change something in my input latex file to handle this input
different than what I am doing now?
