Is it a known issue that scrolling through a discussion sometimes behaves "erratically"?
Here's a video:
What I'm doing there is simply scroll down with the mouse wheel, but sometimes the stream decides to "focus" a post so it goes up instead.
EDIT: now it also happened that while scrolling, the current post number became 1 for a moment, until I scrolled again.
EDIT2: happened again, here's the output of app.current.get('stream')
while the post number was 1. (I still have the tab open with the bug, if needed ahah.)
