Fix infinite scroll when "Upcoming livestream" appears (#665)

Browse source 
## Issue
When "Upcoming livestream" appears in a list, infinite scroll stops working.

## Cause
The difference between `mainEl.getBoundingClientRect().bottom` and `window.innerHeight` became slightly greater than 0.5, so it was deemed as "haven't reached the bottom".

## Change
Coincidently, I've been wanting to make the inf scroll load earlier (instead of after reaching the absolute bottom) to make the experience smoother, so added a 200px threshold, which is roughly the height of a tile. This gets us the new behavior while also fixes the original problem.
