I see several problems with the "full page".

First of all, the URI was broken at a line-break; and only the part in
the first line was recognized. This was 404. I had to copy both lines
and piece the URI back together. Per RFC 3986, the URI should be
bracketed with < and >. This is especially important with long URIs.

Next, the use of escaped characters (e.g., %2F for /) is unnecessary and
might cause problems. The W3C validators work better with HTML markups
for characters that might otherwise require escaping (e.g., &amp; for &,
&lt; for <).

I suspect the itunes:image part.

What's another word for thesaurus?

In article <b48foa....@news.alt.net>,

Above address on my Mac's Safari gets nothing; but my iTunes app
springs open! The iTunes app has big ears and heard itself mentioned.

itunes:image would be an unusual (proprietary) element.

Best to use very like:

<img
src="https://i1.sndcdn.com/artworks-000315700317-eyx9n5-large.jpg"
alt="">

It's the 's' in the protocol (http_s_). See the discussion at:

The latter gets a Safari can't open the page on my coputer. Whereas

<https://i1.sndcdn.com/artworks-000315700317-eyx9n5-large.jpg>

gets a cup of coffee.

What would you rather have first thing in the morning?

Well, even if it were true that Safari was written in CoffeeScript,¹ it
don't mean that she will open just any latte.

Can't prove it but, it's probably the difference betwixt latte and
espresso. Or a quirk in Safari, as I get with my FF as many cups as
there are hrefs pointing to them.

An early "can't open the page" is always refreshing, but nothing beats a
hot cup of Java :)
