.animate() css left and right on a 100% width box using percentages doesn't work correctly in Firefox

When you animate right: '+=100%' it works fine, however when you animate it back: right: '-=100%' it fails.

Works fine in 1.7.2, but not in 1.8.0 or 1.8.1

Also seems to work fine if the box isn't 100% wide.

Sorry, doesn't work if #outer box width is any percentage, but works if the width is set in pixels

using Firefox 15.0.1

What exactly does it mean to animate right: "-=100%" ?
