Browsers effected: Internet Explorer only (tested in version 9)

Description: Building an accordion plugin, the "Promise" function appears to re-set numbered bullets to zero following animation.

In the JSBin example, follow the steps below in Internet Explorer to re-produce the issue

• Click the "Heading" 1 text to expand the hidden text for section 1
• Click the "Heading" 2 text to collapse the section 1 text and expand the hidden text for section 2
• Click the "Heading 1" text again. The section 2 text contracts, section 1 text expands, but this time the numbered bullets have been reset to zero

Upon removing the surrounding "Promise" method, the problem does not happen.

In Firefox 4 on OS X 10.6.7, the line below caused a JS error of "regular expression too complex":

$("#top *[contenteditable=true").keyup(function() { return false; });

Adding in the right bracket fixed it, as follows:

$("#top *[contenteditable=true]").keyup(function() { return false; });

The first version did NOT throw an error in FF 3.6.16 (or any tested version of Chrome or Safari).

Recently some of the websites we built all came with the error "Script3: Member not found" in IE7-8, and it's a nightmare...
