Bug: clicking a link from the home/all feed, then backing out causes jump to beginning of feed

If I click into a post, then the link, then try to back out, it goes back to the post and then goes back to my last position in the feed, as expected. But after clicking a link directly from the home/all feed, when I try to back out it no longer keeps its place, instead jumping back to the top of the feed. Using the voyager app on iOS.
