While it's clear this is a problem, it's less clear that it's actually fixable in a reasonable way, plus it seems like something that is less likely to happen in practice, so marking p5.

Another example:

https://www.salon.com/2017/12/13/trumped-up-charges-feds-try-to-criminalize-inauguration-day-protest/

Salon is practically unreadable without reader mode-- and ends up with the wrong articles in reader mode.

Just loading this page and then entering reader mode seems to use the right article. Does this issue only happen when scrolling to the bottom or something?

I can't get it to load any more. I had tried to kill some of the migraine triggers before I tried reader view.

I have another example, where the 2nd article is not loaded as XHR (same bug or different?):

https://www.lifehack.org/articles/lifestyle/your-perception-is-your-reality.html

Firefox reader mode loads the "keep on reading" article at the bottom (which is randomly chosen each time you request the url). The actual article is not show in reader mode - only its title / heading.

Firefox 62.0b7 on Android 8.1.0.

Also, it brings you not to the original page but to the lazy loaded article instead if exit after you load it first then enter reader view.
