[luatex] Synchronize ERROR: unknown node type 11

[Jérôme LAURENS]

Hi

I suspect this might not be the best location for a bug report, but I could not get mantisBT to work.
This bug stands around since 2019 (https://github.com/jlaurens/synctex/issues/30)

Source file `bug.tex`
```
\mathsurroundskip=1cm
$y$%
\bye
```
## Command
```
luatex --synctex=1 bug.tex
```
In the terminal output below all the `Synchronize ERROR` lines are unexpected, they are not ini the log file:
```
This is LuaTeX, Version 1.18.0 (TeX Live 2024) 
 restricted system commands enabled.
