I am writing a widget to re-use the git repository page.
When consuming the widget outside of Orion, in Chrome, I found that if the html document is scrolled(which is not reproducible in Orion as all the pages in Orion are inside the working target DIV), the command tooltips are far away from the commands.

It only happens in Chrome(version 40. Not sure if it happened in the previous version).
It turned out that the littlelib.bounds uses document.documentElement.scrollTop, which is always 0 in Chrome.
The littlelib.bounds API is used in the tooltip positioning API so it causes offsets.
