Freeze on export if mesh contains hidden faces

[CrushaKRool]

Seems like Blender just freezes on export if the mesh contains faces that were hidden with the H key. Unhiding all faces with ALT+H seems to resolve the issue, but it would still be good if there either was an option to do this automatically on export or if the underlying problem could be fixed altogether, so it either ignores those faces or exports them without problems.

If required, I could attach a .blend file to reproduce the issue.
