6068	Accordion: IE9 B gives null references on paddingTop and paddingBottom	jmiller		"Given fxAttrs = [""height"", ""paddingTop"", ""paddingBottom""], (line 535) and an accordion that has been been clicked and is trying to expand...

var parts = ("""" + $.css(options.toShow[0], prop)).match(/^([\d+-.]+)(.*)$/); (line 548-ish) is setting parts to null for each of the paddingTop and paddingBottom attributes in IE9 (Beta 1 using IE9 Standards mode), which throws exceptions when setting showProps[prop] circa line 550 and again when accessing each of the showProps values circa line 572.

This can be sort-of worked around with a null-check on the setting of showProps[prop] circa line 550, like ""if (parts == null) { showProps[prop] = { value: 0, unit: ""px"" }; } else ..."".  It doesn't quite look right, but it's mostly right and not throwing errors.

(The priority may be wrong if IE9 changes its behavior prior to release.)"	bug	closed	major		ui.accordion	1.8.4	wontfix	ie9
