Scrolling is in excellent shape

• It's fast (throttled, and doesn't require significant paint calls in browser)
• Scrollbar starts after the sticky column/header (instead of being on top of it)
• Works well when mouse is plugged in and when it's not
• Scroll bar smoothly keeps up with scroll location

Better scrollbars

Scrollbars now are now displayed on top of sticky headers and the sticky column.

Debouncing the position of the scrollbars was necessary for performance reasons. They're not ideal, but they weren't functional before because they would hide under the sticky header and column.

Ideally:

• They wouldn't be on top of the sticky elements and would start after them
• They wouldn't have to be debounced and would be fast

This will likely be improved in the future.
