Ok, I can confirm, but it took me a while to find the nature of the bug.
we're expected to use os/2 sTypo metrics for ascent and descent.
https://www.w3.org/TR/css-inline-3/#ascent-descent
However, for line-height we need to multiply by font-size
(https://www.w3.org/TR/css-inline-3/#propdef-line-height) for percentage and
number values.
This is a problem because Noto's em square is 1000 divided into 800 ascent and
200 descent, but its metrics are set to 1069 ascent and 293 descent, which is
afaik because it tries to work around bugs with glyphs larger than the
em-square. I'll need to puzzle out how to tackle this.
