I just installed a WriteFreely instance on the fine Eclips.is service. It’s visible at https://writefreely.public.cat/about, where you can see that the following code is stripped of its title attribute, which renders it useless:
<abbr title="Public Universal Base: Libre Infrastructure Community">PUBLIC</abbr>
is wrongly rendered as:
This rendering would be correct for the second or more occurrence on a page, so browsers and screen readers can interpret it correctly. But the whole point of
<abbr> is to make an acronym understandable!
Thank you for your attention, and especially for your great work with minimalism and typography.
