My biggest problem with infinite scrolling in general is it clears scrolling state by browser back or page refresh.

Sometimes there's no good result in the first page, or I want to keep searching for more investigation.

When I find a seemingly interesting result after several scrolls and visit the page but find out it's not what I want, I want to go back to the search result and continue. But after browser back, the result is cleared and I have to scroll several times again. Even if I open the result in the different tabs and keep the search result, it may disappear after browser refresh or restart.
