It seems different: no gap, but line joining is a bit wrong.
And artifacts are also visible at column joining.

I would tend to say that this is a completely different issue:
something buggy in the rendering algorithm rather than the
interpretation of the metrics.

BTW, note that my sample file is an excerpt from Markus Kuhn's UTF-8
demo at <https://www.cl.cam.ac.uk/~mgk25/ucs/examples/UTF-8-demo.txt>.
