Half of the time those sites also lazy load anyway so whatever you're looking for isn't even in the DOM yet

And lazy unload, so you can't find it even if you've already scrolled through the whole thing.

I used to hear it called "virtual scroll", and I remember webpages ballooning in RAM when they didn't do it.

the text content of the site is not what is ballooning the RAM.
