I haven't found any bug that describes my situation or I missed it - there are plenty of them about "privacy fingerprinting".

Definitely not helpful on this page because unlike a small tracking area, it covers the entire screen. Better to remove that element than see it, but it's probably difficult to program that in advance/globally.

<p>Yes, I can't explain it. A script injects that element into the page, but it is "minified" so it's extremely hard to follow.

Yours is a bit inside out, in that the site appears and then disappears, and then doesn't reappear. If you use the Page Inspector to check the body, does it have a rule similar to:
</p><p>opacity: 0
