WeakRef and FinalizationRegistry md doesnt follow site format

[joaquinelio]

Not sure it's a real issue, the article looks ok on chrome maybe should check others, and epub it looks like an incomplete conversion from html to md

• it uses html br and code tags (only the last part of the article)

• it breaks single sentences in several lines, html dont care but it prevent proper media based formatting in md

• no blank lines between sentences, it's not consistent with the rest of the site
