scrolling left/right hard with mouse is hard

[kjk]

When a list of results is wider than screen and long, scrolling left & right is hard because the scrollbar only shows when we scroll the content all the way to the bottom.

This is not a problem on mac pro with trackpad gestures but a pain with a mouse because in order to get to horizontal scrollbar we need to first scroll all the way down vertically.

This is related to our html containment hierarchy. Probably can fix it by setting height of html and body to 100%. Basically we need to constraint parent of results table to window size so that when table exceeds the size, the scrollbar is at the bottom of the window, not at the bottom of the html document.

I tried overflow: inherit and overflow: initial on #output which solves this problem but brings another problem which is the whole body scrolls over sidebar.
