Scroll the documentation panel when it is hovered by the mouse (#3968)

Browse Source 
[Task link](https://www.pivotaltracker.com/story/show/183970810).

Now documentation panel is being scrolled when only hovered by the cursor (you don't need to click on it beforehand).

Tested on macOS with both the touchpad and the mouse.
