Hello, the following MWE produces an error, which looks like it might be a bug: ``` \localrightbox{xyz}% \hfill\break \localleftbox{abc}% \bye ``` Output: ``` This is LuaTeX, Version 1.21.0 (TeX Live 2025/Homebrew) restricted system commands enabled. (./free.tex warning (nodes): attempt to copy free hlist node 399, ignored warning (nodes): attempt to copy free hlist node 369, ignored Underfull \hbox (badness 10000) in paragraph at lines 2--4 [1{/opt/homebrew/Cellar/texlive/20250308_1/share/texmf-dist/fonts/map/pdftex/up dmap/pdftex.map}]) (see the transcript file for additional information) Output written on free.pdf (1 page, 8930 bytes).
