Infinite recursion with subimport, name collision & .latexmain file

[BarrensZeppelin]

Description

When opening an imported file with the setup shown below, the file_reaches_current function goes in an infinite loop.

Steps to reproduce

Create the following files:

main.tex

\documentclass{article}
\usepackage{import}
\begin{document}
\subimport{chapters/}{main.tex}
\end{document}

main.tex.latexmain
<empty>

chapters/main.tex

hello

And run vim chapters/main.tex

Expected behavior

The chapters/main.tex file should open normally and the root main.tex file should be identified as the project root.

Actual behavior

I get the following error message:

Do you use a latexmkrc file?

No

Thanks! It should be fixed now, I think.
