Occlusion-collection occasionally doesn't render enough items initially.

If the collection is given an array that's shorter than it's visible area, it won't display them all. This may have been fixed by removing the "cap to bottom" on the edges check, but I'd like to leave this here until that's certain.

Removing the "cap to bottom" check appears to have entirely eliminated this issue.
