UI effect 'Fold' behaves differently between browsers

[mrkmg]

Browsers tested:

Firefox 8.0 Chrome 15.0.874.121 m

jQuery Version: 1.7

jQuery UI Version: 1.8.16

Problem is with effects.fold

Description: Place a div onscreen with a fixed position, right = 0, and run a fold effect on that div. In Chrome, the fold's slide is to the right, and in Firefox the fold's slide is to the left. Example is here  http://jsfiddle.net/AKbQx/15/.

Possible remedy: Currently there is no option for fold to define what direction the fold slides to. Adding that option would make the effect more useful and consistent.

Without an option to specify which position attributes to listen to (top vs. bottom, left vs. right), this is a cantfix, as FF won't report "auto" for position attributes, making it impossible for us to figure out if top/left was specified vs. right/bottom.
