Last article not marked as read when scrolling in List mode

Small minor UI weirdness. Nothing big but just thought I’d mention it.
I have a few feeds that I have set to view as a List (bottom right in UI).
This works fine … until you click on one to open it you read it which is quite fine.
If you then carry on scrolling the list the last story is then not marked as read (I guess it now doesn’t know where the bottom of the list is maybe), you need to refresh the feed list then you can mark that read (by scrolling past it or I guess mark read manually)
I have Mark stories as read when scrolled past enabled.
It’s a very minor thing and not a biggie at all.
