I believe this was mentioned first in this post: robert.ocallahan.org/2006/10/partia I'm not sure if it relies on the ligature caret positions: docs.microsoft.com/en-us/typograp or if it still behaves as mentioned in the above post.

This seems like the spot where the partial ligatures are drawn: searchfox.org/mozilla-centra. It is then called here: searchfox.org/mozilla-centra
My code comprehension is pretty bad (especially with C++), but it doesn't seem to be using the caret positions.

amazing, I was just looking for this :P codepen.io/jsscclr/pen/OJ will have to find the chromium equivalent - this is ff vs chrome, since you linking to the ligature caret list table made me realise _surely_ this problem would be encountered heaps in other languages!

Yeah when you combine it with composite glyphs (vs. the ffi ligature which is comprised of a single glyph) things would get strannnge. I'm pretty sure you'd get more weirdness with Indic scripts, for example.

Oh you can see some really fun examples of composite glyphs here 🥴
