I first discovered this issue when rendering text in the Scheherazade
font in Firefox. See this bug report:
https://bugzilla.mozilla.org/show_bug.cgi?id=1614575

They said:

> Ah, I see ... it appears this is a bug in the font, but only in its
Graphite layout behavior. If you set gfx.font_rendering.graphite.enabled
to false in about:config, the problem disappears, as we then use the
OpenType layout tables. Chrome doesn't support Graphite rendering, so
the problem doesn't show up there.

> And the problem doesn't occur when using the font served by Google
Fonts (rather than a locally-installed copy) because Google serves a
copy of the font where the Graphite tables have been removed.

> Further confirmation: I see the same bad result if I use the font in
LibreOffice (which does support Graphite).

> So this is not a Firefox bug, it's a font bug; I'll let the SIL team
responsible for Scheherazade know about it. Meanwhile, as a workaround
you can disable Graphite in Firefox as mentioned above.

This confirms that the problem is in the Scheherazade font file shipped
with Ubuntu in the package fonts-sil-scheherazade.
