* Make scrolling to bottom post in topic more consistent
* when using the slider to scroll past the bottom post,
we now scroll to the bottom of the post/page IF the
post height is > the window height (e.g. really long
posts). if the post height is smaller, then we lock
onto and jump to the top of the post
* this also removes the mobile hack that would always jump
to the top of the last post on mobile
* Prettier lint
