If you are at the bottom and you hit the UP_ARROW key one time, the logic still thinks we are at the bottom, despite the component has clearly moved. Similar to the issue noted in the previous commit, this causes the page to increment incorrectly.
My wild guess is that the previous logic depends on the css height, so it might got broken due to css changes. Hopefully the new calculation is more robust and works for all cases.
---The bad scenario:
If you're at the bottom and you go up using UP_ARROW or HOME key, the coordinate is still at the bottom if we service the callback immediately. This causes 'contentWrapperAtBottomOfPage' to be true and we ended up incrementing the page unnecessarily (even for searches that no longer yield any extra results).
---Fix:
Fix by adding a delay. The value can probably be fine-tuned further.
