Andre (and list),

EB Garamond is hopelessly broken with respect to hlig and dlig, and has 
been for quite a while.

I reported the problem 
(https://github.com/octaviopardo/EBGaramond12/issues/20) over five years 
ago, and the maintainer (if there is one) has done nothing. See also #4 
in that issues list 
(https://github.com/octaviopardo/EBGaramond12/issues/4). There are a 
couple of forks, but there is no established reference implementation 
that I can see. The Google Fonts implementation is similarly challenged, 
perhaps worse.
