The interesting parts in a Bluesky HTML look like this:
<script defer="defer" src="/static/js/792.36c6a7b2.js"></script>
Now, what can we expect to happen if a local HTML contains such a line?
Drumroll – nothing. Nada. Zilch. The script is supposed to be located at /static/, and that location does not exist on the local machine. OTOH, if you look at the document when it’s coming from Bluesky, this URL will be resolved to
https://bsky.app/static/js/792.36c6a7b2.js
which is a perfectly fine location – the browser knows how to load that. But the (expletive) programmers over at BS didn’t think to set the base element in their HTML. Stupidity? On purpose?
In any case, no browser has a chance to display this HTML locally. I tried with Safari and FF – the important thing, namely the BS logo, appears, of course. Marketing rulez.
That’s another good illustration why trying to use HTML as a local archiving format is not a good idea.
