fix always-scrollbar in chromium browsers

horizontal scrollbar would display in chromium browsers,
 no matter the content.

Now it only displays when there is content to scroll (in /managed)

This was an oversight; I set overflow-x: scroll to verify something
 and - since firefox doesn't render the scrollbar anyway -
 forgot to change it back.
