This bug (https://github.com/behdad/harfbuzz/issues/180) was fixed on 17 December 2015. It was present in at least HarfBuzz Versions 1.0.1 and 1.1.2, and was gone in Version 1.1.3.
It's been annoying me in LibreOffice for some time now. The problem is that I'm using a long-term-support version of Ubuntu, 16.04 Xenial. Xenial's distribution provides Version 1.0.1 of HarfBuzz - Package libharfbuzz0b Version 1.0.1-1ubuntu0.1 to be precise. We can cite it for at least two living scripts, Balinese and Tai Tham (for Tai Khuen - example string is ᩉ᩠ᩅᩯᩁ /wɛːn/ 'ring (n.)'). Should one hope to get it fixed for Xenial? Alternatively, should I add a work-around to my OpenType Tai Tham font, which just about works, despite USE. (An alternative is for Xenial users to replace libharfbuzz.so.0 by a newer shareable object without going through the repositories.)
