I can confirm the problem.
However Blender 3.1.0 has a new much faster obj exporter (you can download at https://builder.blender.org/download/)
As the old exporter might be discontinued at some point, I'm not sure if it will get fixes.

The new OBJ exporter (since Blender 3.1) exports the file correctly. The old python based exporter is likely to get removed soon, and very unlikely to get fixes.
