Going to Home puts me at random place in list

I'm not really sure how describe this. Since about 2.37.2, whenever I go back to Home after being on one of the other tabs for a short while I end up in a different place from the one where I left Home.

I have marking as read on scroll turned on and I can see that the posts above my new position are unread.

I'm on the Android app and it still happens in 2.39.0.

Edit: Also, pressing Home to get to the top of the list doesn't work anymore when that happens. It just goes up a few posts at a time.

Edit 2: Just realised, the tab is called "Posts".

Edit 3: It doesn't happen when I'm on a post and then go back to the list.

Edit 4: Just happened after going back from a post.
