Change the threshold line for where a comment is "seen"
Since the threshold for having "seen" a discussion is at the page's 50% vertical line, there are situations where a user might load into the page and immediately mark a discussion (or multiple discussions) as seen.
The Jump To Next Unresolved Discussion button will then go to the next discussion.
However, because a user action didn't mark the discussions as "seen", the Jump button will go to what is probably an unexpected location; the user is probably expecting to go to the first unresolved discussion the first time they click the button.
We should move the threshold to a location that minimizes the chances of this occurring, or set an exclusion that doesn't mark discussions as "seen" until a user has initiated a scroll input.
