Infinite lists scrolling (in)efficiency (i.e. loading on demand)

[dumblob]

Newbie here. I wonder if the web listing (especially images/videos) support "infinite scrolling back & forth"?

Web browsers choke if there are more than ~7 pages of picture content to be scrolled through. As a "solution" (actually a nasty workaround but widely adopted - incl. Google, React, etc.) is to completely remove all invisible DOM elements from the DOM and instead put there one and only one block element of the same dimensions as all the removed elements together.
