Doubly-escaped YouTube links (and possibly others)

[corrideat]

Problem

On https://groupincome.org/faq/ the links to YouTube links are wrong (although not completely broken) as the URL params are double escaped (the links use & instead of &, i.e., the markup is & instead of either of & or &).

Another issue: those links have target="_blank" but lack rel="noopener". Although in recent browsers this is fine because target="_blank" implies the latter, in older browsers that's not the case. I still prefer including it, but it's not strictly required.

Solution

Identify and fix the issue leading to the string being escaped twice. This may affect other links too.
