OK, "Bug" is the wrong word. This renderer/up-scaler is using various tricks and techniques to render the image at a higher resolution than it was ever designed for. Elsewhere it's scaling up the width of a line / size of a pixel so that it looks appropriate, but for whatever reason it's missed a trick here.

I think your expectations are too high! You can't expect it to look as good as modern game art, but it's neat that such an old and tiny game can be made to look much sharper than it originally did.
