Scrolling documentation down scrolls too far, and further than scrolling up does

[aukeroorda]

Summary

Scrolling down in the documentation using ctrl+d scrolls further down than ctrl+u scrolls up. Scrolling down even jumps too far, skipping a few lines.

Scrolling down too far

Note how the lines prefixed with >>> here are skipped when scrolling down:

 suboptimal, they're probably a good enough choice to  
>>> get started.
>>>
 Rust's collections can be grouped into four major 
 categories:                                           

And that when scrolling back up, we don't arrive at the initial location, but a little lower, as we scroll up less than we have scrolled down.

Reproduction Steps

I tried this:

1. space+k to open documentation
2. ctrl+d to scroll down

I expected this to happen:
Scroll down without creating a gap between the current and previous view window.

Instead, this happened:
Right now it scrolls so far down, that some lines below the previous viewing window are now above it, without ever being in view.
