Fix mobile topic-timeline not closing on scrolling past last post (#8730) 

* when we dragged the topic-timeline handle past the last post
  in a topic we were not closing the timeline as we would if
  scrolling to a specific post
* this also fixes the issue where when scrolling past the end of
  the topic with a massive last post, none of the post could be
  seen
