WeakRef and FinalizationRegistry md doesnt follow site format

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

Open the WeakRef and FinalizationRegistry article's Markdown source and compare it with the site's formatting conventions. Check the reported HTML br and code tags, sentence wrapping, and missing blank lines, then verify the rendered article in Chrome and EPUB to confirm the formatting is consistent.
